RE: RPG400-L Digest, Vol 7, Issue 285

+1 on this one. I get a few emails a week with people calling a program
from the command line that calls my MAILTOOL.. of course a couple parms are
email addresses, and they get garbage in the parms.

Trying to explain this is an IBM "feature" and not a bug in my software is
often confusing to say the least... to the customer.

Using a SBMJOB to call program with parms that exceed
32-characters in size
but less than 32 characters in non-blank data in those fields.

Turns out that if a CL uses SBMJOB to call another program, you can pass
"small" parms without issue. Passing "ABC@xxxxxxx" as an email
address in
a 32 character field works. However, passing "ABC@xxxxxxx" in a 50
character fields doesn't work. The system does not guarantee the value of
the data to the right of the last non-blank character after the 32nd
character. In the 50 character field, positions 33-50 could be blank as
expected, or they could pick up garbage from memory.

Changing the sbmjob back to a interactive call makes the problem go away
(makes debugging fun).

The solution is to make it a 51 character and make the last position a
non-blank character. The called program will receive the 51
character parm
and can then strip out the first 50 character for actual processing.

I can't put my cursor on it at the moment, but yes, IBM does document this
"feature".
