RE: [open-cobol-list] minor preprocessor bug

[William M. Klein]

There is a REAL problem here.  Neither the ANSI Standard *nor* any IBM
compiler supports "partial word replacement"  where a PART of a text word is
"replaced" by COPY REPLACING.

It is TRUE that you can use things like 

  Replacing ==(part-of-word)== by ==New-Part)

to change something like

   This-is-a(part-of-word)

but you MUST use specific characters "(" ":" or ")" to do this.  That is
because they define text words.

NEITHER the first nor the second "XX" should be replaced in this example
(and NEITHER would be replaced on IBM mainframe compilers) - and that
wouldbe true whether or NOT there was a "space" in pseudo-text-1.

NOTE:  ISO 2002 Standard *does* introduce "leading" and "trailing" options
for COPY/REPLACING, but it still wouldn't do a "replace" with this syntax.
