Switching to awk sounds scary to me. It's quite easy to break
awk on OpenServer.

I've got some info on limits of awk from a SCO engineer on OpenServer
& UnixWare that may be usefull if you switch to awk.

OSR5 awk has an input record limit of 3K bytes.
UW7 awk has an input record limit of 5K
And the awk string limit -- 401 limit in OSR5, 5K limit in UW7.
