7.3 Unit-Level Parameters

Unit-level parameters control CA MICS IMS Analyzer
processing.  These parameters are stored in the
prefix.MICS.PARMS library associated with each database unit
you define. The parameters are incorporated into the CA MICS
system by the parameter generation process (IMSPGEN).  Note
that you must run the generation processes for these options
to take effect.

Figure 7-3 identifies each of the system code generation
processes for the IMS Analyzer, their PARMS member inputs,
and the output MACROs (a member may contain the definition of
more than one SAS MACRO) and FORMATs that they generate.  The
output libraries are at the database unit level (prefix)
unless noted otherwise.  The input PARMS members that must be
completed prior to IMSPGEN execution are identified below.
