$txt = FileRead("1.txt")
$txt = StringRegExpReplace($txt, '(.*\R){19}', "")

Msgbox(0,"", $txt)

:)

I really like that creative use of stringregexpreplace there, but im having trouble understanding exactly what it is doing.

the result when i test it is as expected, but the syntax you used doesnt seam to match the help file, and i cant figure out what "pattern" you are actually telling it to look for. i could find  r  in help file but not  R

this is my first time even looking at stringregexp and now i have a headache. :alien:

edit: just looked in the online help file, which apparently has a LOT more info than the help file that opens from SciTE

so it looks like it would match 0 or more of any character that are followed by a carriage return, up to the count of 19, replace them with "" (blank), leaving only what is left over, which would be from line 20 and on?

brilliant!  :alien:
