Subject: Re: Comparing file contents (code included)
Is there a way (since I have the file open) that I can prepend a value (I
need a number to be inserted) onto the line?
Robert
Not sure what 'kind' of number you want. Perl provides the line of the
read file in the variable, $. and I'm guessing you want to prepend
'some' number to your files being read. (VASH, MONH, MANI).
It all depends on what kind of number you want.
If you want to prepend to one of the read files, you could open them for
inplace editing.

I am sorry I wasn't more specific. I meant that for each line that is
going to be written to the file that before that line is written to
prepend it with a number, I mean all lines.
12345 this is the line
12345 this is the next line
12345 this is the next next line
I guess can I re-write the line before it gets written to the file?
