MSIR.0844 Previous undefined macro variable

When the first macro statement was encountered in a request, a possible macro variable (something that begins with ?!) had already been bypassed. For backward compatibility with existing applications, a ?! is assumed not to be a macro variable if no macro statements are encountered. Encountering a macro statement after such a variable has been bypassed suggests that assumption might have been incorrect.

If, indeed, the ?! was simply meant as a literal, it must be changed if macro statements are to be used. If the ?! appears in a comment, it can simply be removed. Otherwise, such a literal must be "disguised," perhaps by breaking it up into two strings that are concatenated using the With operator.
