Esteemed Monks I humbly ask for your assistance,

In searching a flat text file I want to exclude certain rows from processing and copy these lines into my output file. I am successful when a line starts with a “2” as in this example:

if ( $line !~ m/^2/ ) {

I want to be able to do a similar thing when a group of 3 characters is found in positions 14-16, apply certain changes to line before writing it to the output file. My guess is that I would use an if ... then ... else statement and start the logic with something like this:

if ( $line, 14 !~ m/^801/ ) {

I would then define the processing parameters for this match and if no match then the row would be processed as usual.

Any help and advice would be appreciated.
