I am using ma01 on z/OS to create MQ messages from fixed-length records in an existing file. The input record size is fixed at 5078 bytes, but some records have a number of spaces at the end. Consequently, some MQ messages are created with a message length of 5078 bytes, and some are created with a message length somewhat less. I can't seem to find anything in the ma01 doc that indicates how to avoid this truncation. Is there a way for me to do this? Thanks in advance.

MA01 knows nothing of record I/O. MA01 reads files using C stream I/O using something like fgets(). So, if you are going to get this to work I suspect you are looking for a setting in the C runtime on z/OS to cope with the various z/OS record formats. Generally speaking I think it works best when you are using VB rather than FB records. The C programming language itself doesn't understand file records.

If all you want to do is read a FB file and issue an MQPUT for each line it finds then this would be a trivial program to write. You could probably modify AMQSPUT0.C without much difficulty. This might be a better approach in the long run.

Cheers,
Paul.

Or write a simple sed/perl/awk/python/something script to pad the ends of the lines in the file.
