I posted this workaround and then ate it, as it was buggy when I ran
it through a second set of strings. I still believe working around the
problem using STREGEX and its LENGTH variable (to give you two points
in the string) should work in principle, but my code is buggy. Sorry.

RegEx = '\\[^\\]*\.'
StrLen = STRLEN (Res)
ExRes = STREGEX (Res, RegEx, LENGTH = Len)
p1 = StrLen - ExRes
p2 = StrLen - ExRes - Len

Maybe someone smarter than me can work out why my p2 values are
occasionally out by 1, occasionally not.

Sorry it's only a partial solution,
Chris
