MSIR.0654 Macro variable (varname) not defined

A macro variable dummy string (something that begins with "?!") was encountered, but the macro variable after the ?! was not defined.

th The likely causes of this are;

• A ?! occurring by happenstance in a comment. Change the comment to say have a space between the question and exclamation mark,
• A misspelled macro variable name. Correct the macro variable name.
• A macro variable name that just isn't defined sometimes for the code that contains the dummy string. Embed the problem clause in a macro !If block.
