Ah, yes, the cerebral flatulance syndome... :-)
If I understand what you want, what you will be happier with is using
markers and parse/all.
rule: [thru "x" start: to "z" ending: (a: copy/part start ending) to
end]
parse/all "x .... ab z cd y" rule
print a
Of, course, if I didn't understand what you wanted, and can't figure out
the adjustment, give the list another yell.
