I agree that it's a fullword of zeros. But, this demonstration is not JCL
In memory only the first halfword "counts". But since the area of the halfword is somewhere not just
2 bytes of the end of the page, and L shows 4 bytes ..
The calling conventions of test and jcl are not different unless during the last 49 years I have
missed a change (which would have created some not so small incompatibily problem.)
As S.M. said, everything after 2+length is irrelevant.

For EXEC PROC=, the default is no PARM override. For EXEC PGM=, the

What's the default value for the optional PARM= on the JCL EXEC

It doesn't appear in the JCL Ref. (haven't checked the cited "Assembler
Services Guide.")
