The first line (unless NOLIST is specified) in the message output begins with the following format:
SYNCSORT FOR Z/OS n.n.m.tci U.S. PATENTS…where:
n.n - Indicates the release number (for example, 3.1).
m - Indicates the TPF maintenance level.
t - Indicates the TPF sub-level.
c - Is either N or R, where N indicates a non-resident configuration of MFX, and R indicates a resident configuration.
i - Is either I or a blank, where I indicates a program-invoked sort, and a blank indicates a JCL-initiated sort.
For example, a header line containing 3.1.1.0RI indicates that the version of MFX that was executed was Release 3.1 at the TPF1 level of maintenance; that it was installed as resident; and that this execution of MFX was invoked by a program.
Release information in the header indicates the latest maintenance level applied.
