Unexpected behavior defining empty MACRO #36
Description
The following works fine:
MACRO
&LABEL FISHTEST &whatever
MEND
END
ISSUE 1:
The following causes an INTERNAL ERROR:
MACRO
&LABEL FISH_X &whatever
MEND
END
Notice the macro name contains an "_" (underscore). This results in:

ISSUE 2:
The following minor change causes a compilation error:
MACRO
&LABEL FISH_X &whatever
MEXIT
MEND
END
Notice I added a MEXIT immediately before the MEND. This results in a "operation field contains an invalid char: _" compilation error:

[2] @[2]-1 operation field contains an invalid char: _
If I then remove the underscore:
MACRO
&LABEL FISHX &whatever
MEXIT
MEND
END
Then it works fine!
I could not find any mention anywhere in the documentation regarding "_" (underscore) being an invalid character for a macro's name. Is this a bug in ASMA? Or an undocumented limitation of ASMA?
Thanks!
