#pop

This command can be used to restore macros or rexx variables from a stack. This is useful for recursive type applications.

Syntax

    [WhiteSpace]#pop  ["]Type["]  ["]Item["] ...
    

The "Type" parameter is used to indicate what sort of information is being popped. This should be "MACRO" for macro values or "REXXVAR" for rexx variables.

You may specify one or more "Item" parameters. These are popped (with StackPop()) off the stack in reverse order (from right to left). The reason for the reverse order is so that you do not have to manually reverse them yourself and possibly making a mistake.

The items were probably originally placed onto the stack with the #PUSH command.

Example

    ;---Set rexx variable and Save ---
    #RexxVar RxVar = 'Demonstating overlap'
    #push RexxVar RxVar
    
    ;--- Set macros and save value ---
    #define  FirstMacro   Something1
    #define  SecondMacro  Something2
    #push macro FirstMacro SecondMacro
    
    ;--- Restore The rexx variable ---
    #pop RexxVar RxVar
    
    ;--- Change Value ---
    #define  FirstMacro   SomethingElse1
    
    ;--- Restore Values ---
    #pop macro FirstMacro SecondMacro
