The first 14 lines are from the same source file as the rest of the script. To clarify, for the source/input file I need the first 14 lines, then anything that stars with LX* and ends with CAS* only if 00003 is in between those values, then I need the last three lines of the file.

Good point on the "$lines" variable. I'll have to re-write that portion. I'll you all know once I've done more testing. EDIT: I think that the script can't find the file, or can't open it, but is not throwing an error.

I apologize for the haphazard order of replies. I am getting used to this forum's format.
