No, -80 BEFORE is just 79 AFTER plus the one character matched by the xrange. The tiny trick of using BEFORE is just not having to adjust the length to account for that one character. > Is that .. | x: if chop -80 | x: | ... ? The equivalent to that (minus the extra null records) would take *another* tiny trick I use all the time with CHOP to *generate* null records. To work around "-0 is not a snumber," I look for a character that doesn't exist: ... | split 80 before not 00-ff | ... ¬R
