Note that this is just off the top of my head and I haven't debugged it.


The in comming file is variable length records. Each record is separated by CRLF. So I have to read each character until I my counter reaches 80 then start over on a new line, or until I reach a CRLF then start a new line.

The output will have a maximum of 80 character per line.

I am looking at the FGETS(). Maybe I can process each line one at time.

Thanks,
