The SYSLIB DD statement was originally needed to resolve the references for ETRSINIT and ETRSFINI. The ETRSINIT and ETRSFINI modules are required to establish the environment for the EZT program and to invoke the EZT runtime.
Now with apar RO03132, the SYSLIB DD statement will no longer be required in the JCL when running a link edit of an Easytrieve application program. Also, with this fix applied, the presence of the NCAL parm on the link edit will be accepted with no execution-time errors.
One exception to this is for EZT application programs that specify DLI statements. Link edits of those programs will still need the SYSLIB DD that references the IMS library that contains the ASMTDLI module.
