Re: Anyone care to chew on this for a bit? -- RPG400-L

VARCHAR(65000:2) with two byte header is 65572 max (Small
Integer-Unsigned).
VarChar(65000:4) is limited by amount of memory allowed in RPG program
around 4 or 5 MB. 4-byte integer. Max value 2 billion something.

Not sure what you are doing with procedure declaration.

dcl-proc Proc1;
dcl-pi *N VarChar(2000) RtnParm;
Parm1 VarChar(65000:4) Const;
Parm2 Int(4) Value;
end-pi;

MAX_VARCHAR2 is a literal.

Aren't VARCHAR fields limited to 32765 (or something), with the first two
bytes defining the field's length?

What about this? SHouldn't the PI header have the procedure name and
return code only?
dcl-pi *n Varchar(MAX_VARCHAR2) RtnParm;

Everything you need is here. In the real program, the procedures are in a
service program, and the constant is in a separate header file. But I

have

consolidated it all down into a single program that exhibits the problem.
The error is:

I don't see anything wrong with this.
But it gets better, change the value in matterid to '12345-001' and the
program runs fine!!

Here is that output:
