Re: program data structure pointer error

Pardon my noobness here... but what is the parms *parms for? That is
what is causing your error. I use the PSDS as is most of my programs but
i haven't ever used or seen the parm *parms. But then again, I'm not an
expert on this either, just thought I'd ask.

Subject
program data structure pointer error






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
