Re: program data structure pointer error

What was the change?

How is the program called?

The *PARMS in the PSDS (along with %parms()) require that the calling
program pass at least a minimal operational descriptor (aka op-desc).
They _should_ return -1, if op-desc is not there...but...

What's right before the psds in the code?

What's the PI or *ENTRY PLIST for the program look like?

I was debugging a program and after making a change I got a very unusual
error.  I was eventually able to get rid of the error but I don't
understand it.

If I comment out the program data structure it works.
D*               sds
D* jobusr               254    263
D* parms            *parms

but when I remove the asterisks a call to the program returns you to the
menu with no error message.
A breakpoint at the first instruction in the program isn't reached.
D                sds
D  jobusr               254    263
D  parms            *parms

The joblog shows...
Pointer not set for location referenced.
Pointer not set for location referenced.
Pointer not set for location referenced.
Exception recursion detected.
Application error.  *N unmonitored by *N at statement *N, instruction
 X'4000'.

Changing the sequence of the specs has the same result
D                sds
D  parms            *parms
D  jobusr               254    263

Comment out just the located variable and it works
D                sds
D  parms            *parms
D* jobusr               254    263
