Replaced in string literals. But according to what CCSID? I'm trying not to
envision the anguish of the compiler writer confronting something as basic as:
printf( "??( ??/??/ ??)??/n" );
The ISPF Edit Macro Ref. states that metacharacters in regular expressions
are interpreted in the code page of the logged-in terminal. It lists a
couple dozen that are supported. A challenge to the author of purportedly
portable macros.
What if batch; no attached terminal? A cursory experiment indicates
compatible with 1047. Maybe. Not documented. To make Edit macros
portable, they'd need to provide a PRAGMA CCSID.
I hate EBCDIC!
