ISPF Edit supports regular expressions, now, sort of, with some conspicuous
deficiencies.
Code pages intrude. The metacharacters in regular expressions are interpreted
according to the code page of the attached terminal. Even in a macro. So the
programmer would need to supply an instance of each macro for each supported
terminal code page. Or translate (iconv()?) any regex from a canonical code
page (1047?) to the active code page.
It is not documented which code page is presumed if Edit runs in background,
with
no terminal attached.
Java has its own support for code pages.
