RE: Getting a MCH3601 Pointer not set

The other alternative is in the called program to check that the number of
parameters passed is at least 5 before using the 5th parameter.

I looked at the change dates at the end of the source. When I put a
parm5 CHAR(1) value (' ') the program works

Yes - and it sure as heck hasn't been "working" with only four parms.

Somebody is telling you little porkie pies.

This code has been around over 20 years and is suppose to the work.
The CL program is only passing four parms to the rpg program that has

a

plist of FIVE PARMS.

Could this be the problem? Did not write any of this.

Are you passing three parameters when calling the program?

I have the following:

D-specs
D wrunc s 1

Getting this in the definitions per compiled listing

WRUNC A(1) 009800D 011400 0390
BASED(_QRNL_PRM+)

*entry plist
parm ONE
parm TWO
parm wrunc

Now in the C-specs
if wrunc = cspace

When I hit this line inside debug or not in debug mode I get a

Pointer not set for location referenced.
Function check. MCH3601 unmonitored by PROGRAM_NAME at statement

123456.

In my AS400 COBOL days a MCH3601 came from not having the file that

had

variable in the record OPENED.

Not having a good day. Lots of internet ups and downs.

Other issues.
