`/B(?:3[89]\|4\d)/` [download] This worked like a charm, and really helped me understand the proper syntax of the conditional test. Thanks much! CT Charles Thomas Madison, WI	[reply] [d/l]

`(?(?{code}true-regexp) (?(?{code}true-regexp\|false-regexp) / B (\d\d) (? (?{ $1 < 38 \|\| $1 > 49 }) # if invalid (?=A)(?=Z) # then fail # else succeed ) /x` [download] It could also have been written: `/ B (\d\d) (?(?{ $1 >= 38 && $1 <= 49 }) # if valid # succeed \| # else (?=A)(?=Z) # fail ) /x` [download] `(?=A)(?=Z)` means the next char must be an 'A' and must be a 'Z'. That's never gonna happen.	[reply] [d/l] [select]
