PPWIZARD is a free preprocessor for HTML, REXX, Visual Basic or any text files.

\ -> Macros -> Macro Transformations -> $$ISBLANK


This is a transformation that can be applied to the substitution of content for both macros and macro parameters.

This will substitute "Y" or "N" for the text. "Y" of course means that the macro or parameter value was not empty or all spaces.

This would probably be used in a "#if" or similar command where you suspect that the value might expand to multiple lines (which the PPWIZARD commands can't handle).

EXAMPLE - Extract From Macro

#if ['{$Parm1='' $$IsBlank}' = 'N']
