@mkeintz - Nice correction, but then I realised my attempt doesn't doesn't cater for multiple sets of parenthises so I think that a DO UNTIL (or WHILE) loop is still needed for that case.

@SASKiwi   I don't think a DO loop is required.  My understanding is that all text from the left outer paren through the right outer paren is to be eliminated, leaving the leftmost "word" preceding the first "(" and the rightmost word following the last ")".    No need to account for interior parens.

@mkeintz - This is the case I looked at

Have:

AAT(BB)ADAA(CCDC)AXC 

Want:

AATADAAAXC

Your solution gives: AATAXC

Ah.   Right you are.

@mkeintz - I thought about it long and hard and realised that any non-PRX solution is likely to be no better than the PRX one 🙂
