DCL WRITE/SYMBOL Failing - Bug?

Robert Atkinson — Wed, 24 Aug 2005 05:27:36 GMT

Here's a great one for you!

I have a set of routines (DCF) designed to handle files and records. The routines work fine across the system.

I've recently decided to take advantage of the 7.3-2 increased DCL limits and am writing a record of 500 bytes.

As you can see, the attempt to write a record fails. If I then close the file, re-open it and retry the write, it's sucessful.

I suspect this is an internal DCL/RMS bug, but I'd like your opinion.

If anyone's interested in the full code, drop me your email address to ratkinsonuk_at_tbs-ltd_dot_co_dot_uk.

$ !
$ OPEN /READ /WRITE /SHARE /ERROR=OPEN_MASTERFILE_ERROR OUTFILE DSK$EMAILDIST

Ignore me (having a stupid day). I was opening the file twice, once read only and the write, hence the FAC error.

Robert,
"bad days" remembers me a song of REM.
Stop your work for a while and give your congratulation to some promote gurus in this forum.
Have a nice day!

This leaves the question, why the procedure didn't proceed to the error label.

Note:
I normally add a CLOSE/NOLOG... before every OPEN, just in case.
