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

Which statement is in error?

Would do this:

dcl-c MAX_VARCHAR2 32767 INZ;

Initialize.

The error is RNX0115. Length of varying length variable is out of range.

Here is a reproduction of the problem:

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:
