By the way, does anyone know if IBM *has* increased the number of Work Control Block tables from thirty? That could explain the problem.

Hi Richard,

this was code that I obtained from Tim McCarthy when he was at Trailblazer
systems ca. 1996. I've never debugged an MI program before. Any tips on
how to do this?

To begin with, you need a compilation listing. Debugging is through the
OPM debugger, by hexadecimal instruction number; all variables can be
accessed through DSPPGMVAR unless their names start with periods.

When setting breakpoints, use the instruction number (I don't have a
compilation listing in front of me, but I believe it's the second
column, the one that shows an ascending sequence of hexadecimal
numbers). For example, if the instruction of interest is at instruction
number 002D, then you would set your breakpoint at '/002D' (including
the slash and the single quotes, to tell the debugger that you want an
instruction number rather than a HLL statement number).
