Starting from r14.0, the program OPAME010 was moved from CCLXLOAD to CCLXPLD due to rewrite in LE/C.
There is a reference in the OPS/MVS documentation at the following link:
Install the OPS/MVS UNIX System Services Syslogd Server
that indicates:
..The hlq.CCLXPLD load library should not be in the linklist or LPA because it is only used by the USS Syslog Server and is an unauthorized PDSE..
So, it will be no longer possible to execute commands like TSO OPAME010
How to fix this behavior that was working correctly in the previous releases.
All the AME source was re-written in C and the resulting load module was then assembled/complied as a program object, which as such needs to be in a different load module dataset than non-program object modules, like the majority of older OPS/MVS load modules. The CCLXPLD library is used for program object type modules, so this dataset is not just for USS. Code has been added to the CCLXPLD load library for some time now, as it contains modules for the SOF feature and modules for use by the OPS/MVS 'web' features.
The Labs have checked and they do not see any reason why the CCLXPLD load library can not be in Linklist or LPALIB. The reference in the OPS/MVS documentation will be updated/removed.
