Jon,

So in a way you're asking for both Value and Const to be allowed on a parameter.

I use Value itself so rarely, I'm not sure if I'd ever use what you're asking for. But maybe I need my mind expanded.

Subject: Re: [WDSCI-L] CONST parameter changed?

CONST will not cause a copy of the passed variable to be made unless there is a data type/size mis-match. Consequently, since you have no such mismatch, the parameter passed is the pointer to the real atrval variable. Since that is global the rester will indeed cause it to change value.

So - Yes - it is perfectly normal. Unfortunate but normal.

I have long wanted to have a version of const that operates in similar fashion to COBOL's "BY COPY". That causes a copy of the data to be passed regardless - even when there is no type/size mismatch. I believe this capability is on the RPG wish list, but just hasn't risen to the top yet.

Hi group,

I encountered a strange issue today when coding a procedure.

In my main procedure, I call a subprocedure:

WriteAttribute(o_pdmnbr19:
o_vernbr19:
*blanks:
atride94:
atrval20);

In my WriteAttribute procedure, I have the following interface:

Dcl-proc WriteAttribute;

Dcl-pi *n;
pdmnbr_p like(pdmnbr20) const;
vernbr_p like(vernbr20) const;
colint_p like(colint53) const;
atride_p like(atride20) const;
atrval_p like(atrval20) const;
End-Pi;


At one point in the subprocedure, I do a reset of the record format containing - among other fields - ATRVAL20.

As soon as I do this Reset, the atrval_p field goes blank also.

Is this normal behaviour or am I doing something wrong?

I thought that the CONST keyword indicated that your parameter could not be changed...
