I put both forms into subprocedures for a test and am now getting a problem
I don't quite understand.
I was getting this in earlier attempts.
There are 4 subprocedure calls below.
On the 3rd or 4th call ( it seems a bit random ), I'm getting SQLCODE 16402
and SQLSTATE 0169F
and the following message in the joblog:
"The pointer parameter passed to free or realloc is not valid"
Are you connecting to Db2 for i?
I can't find either of those in the 7.3 reference.

I ran your code one million times on my 7.3 machine and didn't have an
issue.
Whoops, too fast post.

My job log does indeed show SQ16402 JSON data is not valid.
When I modify the code to look at SQLSTATE, I see 0169F after the two
runs with JSON data that isn't valid.

I'm sorry for the earlier, wrong answer.
