More information about macros: Macros
Macros are sets of commands which are executed when the macro name is used. They may also be considered a way of adding more commands built from already existing commands. Macros execute in a stack. That is, the most recently executed macro is put on the top of the stack, and it will finish all of its instructions before the prior macro will continue. While running a macro, a currnet macro state is kept. This allows certain commands to return success or failure. Some commands, such as IF, LABEL, GOTO, will only be used in a macro.
A macro is created using the /MACRO command. All commands which are entered after a valid /MACRO command are recorded into the macro. A command recorded into a macro does not require a leading '/', it is assumed that it is a command. To end a macro, the /ENDMACRO command may be used. While a macro is being recorded, the current macro name is displayed on the command prompt.
If more words after the macro name are specified, these will be the names of local variables. If a macro uses the /DECLARE command, new variables will be created only for the current state the macro runs in. If the variable existed in the object before the macro ran, the value in the object will be updated, and a new variable will not be created. A macro may use the alternate form - /DECLARE in Object - to define a new variable in its own object(%me), or another object. Macro parameters are checked first when referencing values, then values in the current macro state, finally variables defined in the object are checked. If the name exists prior to a /DECLARE then that variable is updated.When used in a macro the /REPLY command will send a command like a /TELL to the object which invoked this macro via a /TELL command.
COMPARE may be used in a macro to test the value of variables compared with either a constant value or another variable. After executing a /COMPARE the result is tested with /IF. There are only two outcomes for a compare... SUCCESS or FAIL. Many commands will also set the SUCCESS flag when they work, and all commands(except /IF) clear the flag before being executed.
LABEL may be used to mark a spot in a macro to jump to. GOTO can be used to go to any LABEL defined in this macro. If a label is defined more than one time, only the top one will be valid to jump to.
RESULT may be used to return a value from a macro. Upon returning, the calling macro may use GETRESULT to retreive this value. If the result is not re-set, the last RESULT will be present for all calling macros.
