LERAD

For non-LU 6.2 sessions, VTAM® schedules the LERAD exit routine for errors causing a recovery action return code of X'14' or X'18'. VTAM schedules the LERAD for these return codes, and, in addition, defines several unique recovery action return codes for LU 6.2 support. For cases of a recovery action return code of X'14', the FDB2 field contains specific error return codes, some of which are also unique to LU 6.2 sessions.

The recovery action return codes applicable to LU 6.2 support are:

X'14': Indicates a general logic error. In the case of LU 6.2 support, the exit is scheduled when an application program attempts to issue a non-APPCCMD macroinstruction for an LU 6.2 session and that macroinstruction is not allowed on an LU 6.2 session. Most of these macroinstructions are the instructions used to establish sessions, such as OPNDST.
X'18': Indicates that VTAM cannot complete the request because the RPL address specified on the APPCCMD macroinstruction does not point to a valid RPL or an APPCCMD was issued asynchronously and no exit routine was provided. This return code also applies to non-LU 6.2 macroinstructions.
X'1C': Indicates that the RPL extension is not a valid data area.
X'20': Indicates that APPCCMD CONTROL=CHECK was issued specifying an inactive RPL, or another APPCCMD macroinstruction was issued specifying an already active RPL.
X'24': Indicates that APPCCMD CONTROL=CHECK was issued against an RPL that contained a non-APPCCMD request type, or indicates that a non-APPCCMD CHECK macroinstruction was issued against an RPL that contained an APPCCMD request type.
