7.3.2.2 Define the MSI Input Routine

One of the advantages of using MSI is that there is no input
format routine to code.  In fact, most FDAs using MSI require
no additional coding beyond the fdaGENIN member.

This is not say that FDAs using MSI cannot be modified.  MSI
provides many user exits that allow for customization.

    1 - Original Sysid Assignment Exit (cccSYSID)
    2 - MSI File User Exits
    3 - MSI User Exits
