OP BIGZIPZ Ameglian cow B Joined: Feb 2006 Posts: 22	I am trying to read 10 lines from a text file called Comics.txt and I want it to increase the var %matrhfound by 1 every time it finds a line in the text file which starts with DC: e.g: DC: What Golden Age mystery-man was aided by the Newsboy Legion? This is what I have so far and I cannot seem to get it working, am I missing something? Thank you alias temp1 { while (%iii <= 10) { if (DC isin ($read(C:\Comics.txt, s, DC, %iii))) inc %matchfound 1 inc %iii 1 } }

Preferable would be: Code: alias countlines { var %file = $+(",$1,") if (!$isfile(%file)) \|\| (* !iswm $2) return filter -ff %file nul $2 return $filtered } $countlines(versions.txt,var) $countlines(c:\my files\doc.txt,item) Gone.
