In other contexts, I've referred to the options as horizontal and
vertical consistency. In the case of PCRE, I'd advise sticking to the
Perl syntax for the regexen themselves, but not necessarily elsewhere,
e.g.,
address PCRE MATCH 'fromvar' 'regexvar' ['optsvar' ['capturestem.']]
address REPLACE 'fromvar' 'regexvar' 'subvar' ['optsvar'
['capturestem.']]
Where the parameters are all names and where Perl syntax is used for
the contents of regexvar and subvar. You may want a third form for a
nondestructive replace with a third variable for the result of the
replacement. I'm assuming PCRE would return capture buffers in REXX
compound variables using the default or provided stem.
