Syntax

MERROR | NOMERROR

MERROR

issues the following warning message when the macro processor cannot match a macro reference to a compiled macro:

WARNING: Apparent invocation of macro %text not resolved.

NOMERROR

issues no warning messages when the macro processor cannot match a macro reference to a compiled macro.

Several conditions can prevent a macro reference from resolving. These conditions appear when

a macro name is misspelled
a macro is called before being defined
strings containing percent signs are encountered. For example:
```
TITLE Cost Expressed as %Sales;
```

If your program contains a percent sign in a string that could be mistaken for a macro keyword, specify NOMERROR.
