See $HELP AMOUNTS for details.%r%r %bUse $HELP <topic> for more help on one of: [v(LIST_TOPICS)]%r %bNote: No command prefixes are used in the <topic> field for $HELP.%r
&HELP_AMOUNTS ATM=%b Money Amounts:%r%r %bThe <amount> field of commands can be specified one of two%r %bways.%r%r %bThe first is to use a decimal number, in terms of the primary%r %bcoin of the monetary system, eg. 1.5 meaning [u(FN_MONEYNAME,1.5)].%r%r %bThe second way is to use the coin names or abbreviations, which%r %bare listed in $COINAGE. For example, [u(FN_MONEYNAME,1)], or [u(FN_MONEYNAME,0.5)], or%r %b[u(FN_MONEYNAME,1.5)], or any combination. You can use the singular,%r %bplural, or abbreviation names listed in $COINAGE. If you type%r %bsomething which cannot be resolved, it will be treated as 0.%r
&HELP_GIVE ATM=%b Command: GIVE%r %bUsage: $GIVE <thing>\[=<amount>\]%r %b %b or: $PAY <thing>\[=<amount>\]%r%r %bThis command is used to give players and objects some of your coins.%r %bFor players, <amount> must be specified.%r%r %bFor objects, the <thing> must have an &%vc set, and you must pass %r %b<thing>'s UseLock. If <thing>'s &%vc is less than zero, it accepts%r %bdonations of any size, so you must specify an <amount>. If the &%vc%r %bis greater than zero, only the proper <amount> is accepted - any less%r %bis not enough, and any extra will be returned as change.%r%r %bExample:%r %b> $GIVE Bartender=[u(FN_MONEYNAME,2)]%r %bYou pay the Bartender.%r %bYou get [u(FN_MONEYNAME,1.5)] in change.%r%r %bSee $HELP GIVE2 for help with the &%vg attribute.%r
&HELP_BUY ATM=%b Command: BUY%r %bUsage: $BUY <thing>=<product>\[,<amount>\]%r%r %bThis command is used to purchase a specific item from a vendor,%r %band allow you to specify the price paid. The &%vc-<product>%r %bof the vendor must be set, and you must pass the machine's %r %bUseLock. The <amount> argument is optional - you don't have to%r %bsupply it, and it is just a safety check to make sure you don't%r %bspend more than you are anticipating. If supplied, the same%r %brules as for $GIVE to a machine apply.%r%r %bExample:%r %b> $BUY Bartender=Aspirin,[u(FN_MONEYNAME,5)]%r %bYou buy some aspirin from the Bartender.%r %bYou get [u(FN_MONEYNAME,0.5)] in change.%r
&HELP_DEPOSIT ATM=%b Command: DEPOSIT%r %bUsage: $DEPOSIT <thing>=<amount>%r%r %bThis command is used to store money on an object, like a wallet, or%r %bother secure place (see $HELP STEAL). You must control <thing> %r %b(see Help Control). This is useful for avoiding theft, as well as%r %bkeeping large amounts of money in a vault, etc.%r%r %bExample:%r %b> $DEPOSIT Wallet=2.5%r %bYou deposit [u(FN_MONEYNAME,2.5)] in Wallet.%r
&HELP_STEAL ATM=%b Command: STEAL %r %bUsage: $STEAL <person>%r%r %bThis command is used to attempt to steal money from another person.%r %bThe amount is random - it will be some randomly chosen percentage%r %bof what the other is carrying, with a moderate probability of getting%r %banything at all, and a slightly higher chance of getting caught in%r %bthe attempt. You can only do this to connected players, and if they%r %bare set HAVEN (a typical convention for OOC) it will not work.%r%r %bNOTE: This command may be disabled on some MUSHes.%r%r %bExample:%r %b> $STEAL Reepicheep%r %bYou steal [u(FN_MONEYNAME,0.5)] from [name(owner(me))]!%r
&HELP_COLLECT ATM=%b Command: COLLECT%r %bUsage: $COLLECT <thing>\[=<amount>\]%r%r %bThis command is used to retrieve money stored on an object or player.%r %bYou must control <thing> (see Help Control). This is useful for %r %bcollecting the profits garnered by a vendor, or retrieving money%r %bdeposited in a wallet or vault. If <amount> is not specified,%r %ball of the money <thing> has will be collected.%r%r %bExample:%r %b> $COLLECT Bartender%r %bYou collect [u(FN_MONEYNAME,7.5)] from Bartender.%r
&HELP_CASH ATM=%b Command: CASH%r %bUsage: $CASH \[<thing>\]%r%r %bIf <thing> is not specified, the command reports how much money%r %byou have with you. If <thing> is specified, and you control it%r %b(see Help Control) then the amount of money <thing> has is%r %breported.%r%r %bExample:%r %b> $CASH%r %bYou have [u(FN_MONEYNAME,0.5)].%r %b> $CASH Wallet%r %bWallet has [u(FN_MONEYNAME,5.0)].%r
&HELP_COINAGE ATM=%b Command: COINAGE%r %bUsage: $COINAGE%r%r %bThis command will display a table of the MUSH's coins, and their %r %bdifferent values, as well as a short description of what that %r %btranslates into in buying power.%r
&HELP_COST ATM=%b Command: %vc%r %bUsage: &%vc\[-<product>\] <thing>=<amount>%r%r %bWithout the <product> specification, this is like the standard MUSH %r %bcommand @cost, but the Money System allows you to specify fractional%r %bamounts for the cost of operating a machine. You should also set an %r %b&%vp, &%vo and &%va on an object, to respond when the object is %r %bgiven money, like the @Pay, @Opay, and @Apay equivalents.%r%r %bIf <amount> is negative, <thing> will accept donations of up to the%r %babsolute (positive) value of <amount>.%r %b%r %bWith a <product> named, the object, the $BUY command may be used.%r %bThis makes it much easier for a vendor to sell a number of different%r %bitems.%r%r %bExample:%r %b> &%vc Bartender=[u(FN_MONEYNAME,1.5)]%r %bSet.%r %b> &%vc-Aspirin Bartender=[u(FN_MONEYNAME,4.5)]%r %bSet.%r
&HELP_PAY ATM=%b Command: %vp%r %bUsage: &%vp\[-<product>\] <thing>=<message>%r%r %bThis is like the standard MUSH command @Pay, but is used when the %r %bobject is paid using the Money System. The person giving <thing>%r %bmoney sees <message>. If <product> is specified, then <message>%r %bis seen when someone uses $BUY and specifies that product.%r%r %bExample:%r %b> &%vp Bartender=You pay the bartender, who quickly mixes you a drink.%r %bSet.%r %b> &%vp-Aspirin Bartender=You buy some aspirin from the Bartender.%r %bSet.%r%r $PAY is just an alias for $GIVE. See $HELP GIVE for help.
&HELP_OPAY ATM=%b Command: %vo%r %bUsage: &%vo\[-<product>\] <thing>=<message>%r%r %bThis is like the standard MUSH command @OPay, but is used when the %r %bobject is paid using the Money System. The everyone in the room%r %bexcept the person paying <thing> sees <message>, prepended with%r %bthe payers name and a space. %bIf <product> is specified, then %r %b<message> %b is seen when someone uses $BUY and specifies that %r %bproduct.%r%r %bExample:%r %b> &%vo Bartender=pays the bartender, who quickly mixes %%o a drink.%r %bSet.%r %b> &%vo-Aspirin Bartender=buys some aspirin from the Bartender.%r %bSet.%r
&HELP_APAY ATM=%b Command: %va%r %bUsage: &%va\[-<product>\] <thing>=<command list>%r%r %bThis is like the standard MUSH command @APay, but is used when the %r %bobject is paid using the Money System. When <thing> is paid,%r %bthe command list is run. %bIf <product> is specified, then the%r %b<command list> is run when someone uses $BUY and specifies that %r %bproduct. The %%0 register is set to the decimal value paid.%r%r %bExample:%r %b> &%va Bartender=@create Glass of Mead; give %%N=Glass of Mead%r %bSet.%r %b> &%va-Aspirin Bartender=@create Two Aspirin; give %%N=Aspirin%r %bSet.%r
&HELP_GIVE2 ATM=%b Command: %vg%r %bUsage: &%vg <thing>=<message>%r%r %bThe %vg attribute holds <message>, which only the recipient of a %r %b$GIVE is shown. %r%r %bExample:%r %b> &%vg King=The King hands you some coins.%r %bSet.%r
&HELP_OGIVE ATM=%b Command: %vh%r %bUsage: &%vh <thing>=<message>%r%r %bThis <message> is shown to others in the same location as the%r %brecipient of a $GIVE. For the purposes of code, %%N is the name%r %bof the recipient, %%# is the dbref# of the recipient, etc.%r%r %bExample:%r %b> &%vh King=is given a handful of coins by the King.%r
&HELP_AGIVE ATM=%b Command: %vi%r %bUsage: &%vi <thing>=<command list>%r%r %bThis attribute is used to hold commands to be run upon the %r %bexecution of a $GIVE command. Since the Money System is coded%r %bin MUSHcode, a $GIVE does not run in one "tick" of the queue%r %bas other commands do, and hence there is some need for %r %bsynchronization when dealing with complex vendors. The %%# %r %bregister is set to the dbref# of the recipient, and the usual%r %b%%-registers are similarly set. The %%0 register holds the%r %bvalue given.%r%r %bExample:%r %b> &%vi King=@trigger Grand Vizier/TAX_PERSON=%%#,add(%%0,1)%r

&HELP_AMOUNTS ATM=%b Money Amounts:%r%r %bThe <amount> field of commands can be specified one of two%r %bways.%r%r %bThe first is to use a decimal number, in terms of the primary%r %bcoin of the monetary system, eg. 1.5 meaning [u(FN_MONEYNAME,1.5)].%r%r %bThe second way is to use the coin names or abbreviations, which%r %bare listed in $COINAGE. For example, [u(FN_MONEYNAME,1)], or [u(FN_MONEYNAME,0.5)], or%r %b[u(FN_MONEYNAME,1.5)], or any combination. You can use the singular,%r %bplural, or abbreviation names listed in $COINAGE. If you type%r %bsomething which cannot be resolved, it will be treated as 0.%r
&HELP_GIVE ATM=%b Command: GIVE%r %bUsage: $GIVE <thing>\[=<amount>\]%r %b %b or: $PAY <thing>\[=<amount>\]%r%r %bThis command is used to give players and objects some of your coins.%r %bFor players, <amount> must be specified.%r%r %bFor objects, the <thing> must have an &%vc set, and you must pass %r %b<thing>'s UseLock. If <thing>'s &%vc is less than zero, it accepts%r %bdonations of any size, so you must specify an <amount>. If the &%vc%r %bis greater than zero, only the proper <amount> is accepted - any less%r %bis not enough, and any extra will be returned as change.%r%r %bExample:%r %b> $GIVE Bartender=[u(FN_MONEYNAME,2)]%r %bYou pay the Bartender.%r %bYou get [u(FN_MONEYNAME,1.5)] in change.%r%r %bSee $HELP GIVE2 for help with the &%vg attribute.%r
&HELP_BUY ATM=%b Command: BUY%r %bUsage: $BUY <thing>=<product>\[,<amount>\]%r%r %bThis command is used to purchase a specific item from a vendor,%r %band allow you to specify the price paid. The &%vc-<product>%r %bof the vendor must be set, and you must pass the machine's %r %bUseLock. The <amount> argument is optional - you don't have to%r %bsupply it, and it is just a safety check to make sure you don't%r %bspend more than you are anticipating. If supplied, the same%r %brules as for $GIVE to a machine apply.%r%r %bExample:%r %b> $BUY Bartender=Aspirin,[u(FN_MONEYNAME,5)]%r %bYou buy some aspirin from the Bartender.%r %bYou get [u(FN_MONEYNAME,0.5)] in change.%r
&HELP_DEPOSIT ATM=%b Command: DEPOSIT%r %bUsage: $DEPOSIT <thing>=<amount>%r%r %bThis command is used to store money on an object, like a wallet, or%r %bother secure place (see $HELP STEAL). You must control <thing> %r %b(see Help Control). This is useful for avoiding theft, as well as%r %bkeeping large amounts of money in a vault, etc.%r%r %bExample:%r %b> $DEPOSIT Wallet=2.5%r %bYou deposit [u(FN_MONEYNAME,2.5)] in Wallet.%r
&HELP_STEAL ATM=%b Command: STEAL %r %bUsage: $STEAL <person>%r%r %bThis command is used to attempt to steal money from another person.%r %bThe amount is random - it will be some randomly chosen percentage%r %bof what the other is carrying, with a moderate probability of getting%r %banything at all, and a slightly higher chance of getting caught in%r %bthe attempt. You can only do this to connected players, and if they%r %bare set HAVEN (a typical convention for OOC) it will not work.%r%r %bNOTE: This command may be disabled on some MUSHes.%r%r %bExample:%r %b> $STEAL Reepicheep%r %bYou steal [u(FN_MONEYNAME,0.5)] from [name(owner(me))]!%r
&HELP_COLLECT ATM=%b Command: COLLECT%r %bUsage: $COLLECT <thing>\[=<amount>\]%r%r %bThis command is used to retrieve money stored on an object or player.%r %bYou must control <thing> (see Help Control). This is useful for %r %bcollecting the profits garnered by a vendor, or retrieving money%r %bdeposited in a wallet or vault. If <amount> is not specified,%r %ball of the money <thing> has will be collected.%r%r %bExample:%r %b> $COLLECT Bartender%r %bYou collect [u(FN_MONEYNAME,7.5)] from Bartender.%r
&HELP_CASH ATM=%b Command: CASH%r %bUsage: $CASH \[<thing>\]%r%r %bIf <thing> is not specified, the command reports how much money%r %byou have with you. If <thing> is specified, and you control it%r %b(see Help Control) then the amount of money <thing> has is%r %breported.%r%r %bExample:%r %b> $CASH%r %bYou have [u(FN_MONEYNAME,0.5)].%r %b> $CASH Wallet%r %bWallet has [u(FN_MONEYNAME,5.0)].%r
&HELP_COINAGE ATM=%b Command: COINAGE%r %bUsage: $COINAGE%r%r %bThis command will display a table of the MUSH's coins, and their %r %bdifferent values, as well as a short description of what that %r %btranslates into in buying power.%r
&HELP_COST ATM=%b Command: %vc%r %bUsage: &%vc\[-<product>\] <thing>=<amount>%r%r %bWithout the <product> specification, this is like the standard MUSH %r %bcommand @cost, but the Money System allows you to specify fractional%r %bamounts for the cost of operating a machine. You should also set an %r %b&%vp, &%vo and &%va on an object, to respond when the object is %r %bgiven money, like the @Pay, @Opay, and @Apay equivalents.%r%r %bIf <amount> is negative, <thing> will accept donations of up to the%r %babsolute (positive) value of <amount>.%r %b%r %bWith a <product> named, the object, the $BUY command may be used.%r %bThis makes it much easier for a vendor to sell a number of different%r %bitems.%r%r %bExample:%r %b> &%vc Bartender=[u(FN_MONEYNAME,1.5)]%r %bSet.%r %b> &%vc-Aspirin Bartender=[u(FN_MONEYNAME,4.5)]%r %bSet.%r
&HELP_PAY ATM=%b Command: %vp%r %bUsage: &%vp\[-<product>\] <thing>=<message>%r%r %bThis is like the standard MUSH command @Pay, but is used when the %r %bobject is paid using the Money System. The person giving <thing>%r %bmoney sees <message>. If <product> is specified, then <message>%r %bis seen when someone uses $BUY and specifies that product.%r%r %bExample:%r %b> &%vp Bartender=You pay the bartender, who quickly mixes you a drink.%r %bSet.%r %b> &%vp-Aspirin Bartender=You buy some aspirin from the Bartender.%r %bSet.%r%r $PAY is just an alias for $GIVE. See $HELP GIVE for help.
&HELP_OPAY ATM=%b Command: %vo%r %bUsage: &%vo\[-<product>\] <thing>=<message>%r%r %bThis is like the standard MUSH command @OPay, but is used when the %r %bobject is paid using the Money System. The everyone in the room%r %bexcept the person paying <thing> sees <message>, prepended with%r %bthe payers name and a space. %bIf <product> is specified, then %r %b<message> %b is seen when someone uses $BUY and specifies that %r %bproduct.%r%r %bExample:%r %b> &%vo Bartender=pays the bartender, who quickly mixes %%o a drink.%r %bSet.%r %b> &%vo-Aspirin Bartender=buys some aspirin from the Bartender.%r %bSet.%r
&HELP_APAY ATM=%b Command: %va%r %bUsage: &%va\[-<product>\] <thing>=<command list>%r%r %bThis is like the standard MUSH command @APay, but is used when the %r %bobject is paid using the Money System. When <thing> is paid,%r %bthe command list is run. %bIf <product> is specified, then the%r %b<command list> is run when someone uses $BUY and specifies that %r %bproduct. The %%0 register is set to the decimal value paid.%r%r %bExample:%r %b> &%va Bartender=@create Glass of Mead; give %%N=Glass of Mead%r %bSet.%r %b> &%va-Aspirin Bartender=@create Two Aspirin; give %%N=Aspirin%r %bSet.%r
&HELP_GIVE2 ATM=%b Command: %vg%r %bUsage: &%vg <thing>=<message>%r%r %bThe %vg attribute holds <message>, which only the recipient of a %r %b$GIVE is shown. %r%r %bExample:%r %b> &%vg King=The King hands you some coins.%r %bSet.%r
&HELP_OGIVE ATM=%b Command: %vh%r %bUsage: &%vh <thing>=<message>%r%r %bThis <message> is shown to others in the same location as the%r %brecipient of a $GIVE. For the purposes of code, %%N is the name%r %bof the recipient, %%# is the dbref# of the recipient, etc.%r%r %bExample:%r %b> &%vh King=is given a handful of coins by the King.%r
&HELP_AGIVE ATM=%b Command: %vi%r %bUsage: &%vi <thing>=<command list>%r%r %bThis attribute is used to hold commands to be run upon the %r %bexecution of a $GIVE command. Since the Money System is coded%r %bin MUSHcode, a $GIVE does not run in one "tick" of the queue%r %bas other commands do, and hence there is some need for %r %bsynchronization when dealing with complex vendors. The %%# %r %bregister is set to the dbref# of the recipient, and the usual%r %b%%-registers are similarly set. The %%0 register holds the%r %bvalue given.%r%r %bExample:%r %b> &%vi King=@trigger Grand Vizier/TAX_PERSON=%%#,add(%%0,1)%r
