PUTENV does not call a shell and it is the shell that does the $
substitution.

No - the syntax is correct :-)

EXECUTE does not spawn a shell unless you tell it to:
EXECUTE CHAR(255):"k":"Command to run in korn shell"

You might be better running the cron job via a shell script that
configures the environment. This script, and any other, can source from
a common area:
#! /bin/bash
# Pick up standard environment
#
. /data/envs/develenv.bash
Consult the documentation on the jBASE knowledgebase on these functions.
