It seems that whenever any TSO user are using JCLTRAC to check a JCL member in ISPF EDIT that the following message, with a variety of token values, appears in OpsLog:
JCL2040I IEANTCR RC=0000 Name: "_CA-JOBTRAC_CWA " - Token: 00000000 00000000
PTF SO00396 that corrects this problem. With this PTF on, NODEBUG is now the default if never specified. The DEBUG/NODEBUG option was not documented because it was only to be used when directed by support to display internal
information for level 2 to use for diagnostic purposes. To circumvent this until the fix can be applied specify the keyword NODEBUG on the JCLTRAC command on the Edit screen.
