Re: MI program unable to locate job - need assistance

I'm not sure about V6R1 (or 6.1.0 as IBM now calls it), but up to V5R4 there
is still a maximum of 30 tables.  Each table can have a maximum of 16,352
jobs and the QMAXJOBS system value is limited to 485,000.  Thirty tables can
hold up to 490,560 jobs.  In the job table header object (QWCBT00) there is
a 2-byte binary field at offset 1CB (decimal offset 459) that contains the
count of tables.  On a system with 13 tables:

Dumping QWCBT00 reveals the following:

0001A0   00000000 00000000 00000000 00000000
0001C0   003C0000 0007F600 00000000 0D000000
0001E0   00008000 00000000 234BC6A4 A3000E38

The second line above shows x'000D' at offset 0001CB.  This is decimal
offset 459, or decimal position number 460 (hex position number 1CC).

I've checked this on at least 10 different systems (V5R2, V5R3, and V5R4)
with differing numbers of job tables and this field is definitely the count
of tables.

Using this field is the easiest way of ensuring that you will process all
tables.  To future-proof your code, make the array larger and use the table
count for your limit.
