Robert, we are in MVS land - right?
I have been told that the fact that you can not have the linkage stack in use at entry to LE in VSE is due to missing functionality in the op-sys. My conclusion is: there is some kind of os-macro that tells you depth of linkage-stack in use. BUT- I have no idea what macro that might be. -- Martin Pi_cap_CPU - all you ever need around MWLC/SCRT/CMT in z/VSE more at http://www.picapcpu.de
