Yesterday there was a discussion about a Debug Tool problem on VSE-L. Dovid, thanks for reminding me.   The Debug Tool requires an update, because of the new CICS TS for z/VSE V2 releases. We resolved that issue with an APAR some time ago.   APAR PI75848 (PTF UI44467): ENHANCE DT/VSE WITH CICS TS FOR Z/VSE   PROBLEM DESCRIPTION: This APAR is required to run DT/VSE with CICS/TS for z/VSE 2.1.0 or a follow-on CICS TS release.
