  • Closed as duplicate of another APAR.

Error description

  • Unpredictable results occur in an application after issuing an
    ATTACH. In the description of ATTACH in the z/OS MVS Assembler
    Services Reference, registers 2-12 are defined as volatile
    across the ATTACH and into the subtask. If the application
    depends on the values of these registers but does not restore
    them after an ATTACH, then problems can occur after Debug Tool
    modifies R2.
    

Local fix

  • Save registers before issuing an ATTACH macro, and restore
    afterward.
