[Jozef Zuzelka]

Hello,

I'm doing school project and I've found different behave of these two programs:

$ awk -W version
mawk 1.3.3 Nov 1996, Copyright (C) Michael D. Brennan
compiled limits:
max NF             32767
sprintf buffer      2040

$ echo "02020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020***************************" | awk 'length > 127 {print substr ($0, 0, 127)"\t"$2} length < 128 {print $1"\t"$2}' | tail -1 | wc -c

-----------------------------------------------

I think that mawk is the one with correct output, but I may be wrong. I attached you printscreen witch outputs.

P.S.: Sorry for my bad English :)

I'm looking forward for your reply.
