Ed,
At some point in the past, HP enhanced the JCW's so that when you set a
JCW, a variable is also set with the same name. I believe JCW's are limited
to numbers but a session variable can also hold strings and booleans. So
you can get a JCW or a Session Variable with the HPCIGETVAR intrinsic.
here is an example COBOL that I refer to:
hope it helps...
