file processing ends when ascii code 26 encountered.

[zarleyman]

Whenever my awk program sees a record which contains the non-printable character given by ascii code 26 (), it simply stops processing as if it met the end-of-file.
It does not process the record which contained the ascii-26 character.
(I am using gawk).
I am eternally grateful to anyone who can show me how to avoid this behaviour.
Thanks.

Which Operating System ?
^Z is the end-of-file character in MS-Dos.

Hope This Helps, PH.

Hi,
Thanks for your reply.

I am transferring the file from hp-ux onto windows NT and processing it there.
I understand that ascii-26 is sometimes interpreted as end-of-file. However, many tools (even on windows, eg notepad) just display a non-printable and continue on to all the other records in the file.
If I could get awk to do that it would solve my problem.

Thanks

possible workaround: Can't you let awk on the hp-ux box process the file?

From what I've googled on gawk, it doesn't seem like you can get gawk to ignore the ctrl-Z end-of-file marker...

Hi.
Unfortunately I don't have that facility. All my processing must be done on the windows side.
The best option I can think of so far is to pre-process the files with another tool to search&replace the ascii-26 away.

possibly:

tr -d "\032" <infile >outfile

Thanks p5wizard,
I think that is my best option.
