How to Delete Lines 1 Through 7, Then Last 3 Lines?
Can someone please offer some help on this issue. I am generating some files and within them is erroneous data that needs to be removed. Basically, the first 7 lines and last 3 lines need to be erased from the file.

Any help is greatly appreciated!

You could simplify the LineFindCallback a little if you like...

Function LineFindCallback
Push SkipWrite
FunctionEnd
