Return Code 4

When general-purpose register 15 contains 4, the reason area information is passed back from Catalog Management.

The module identification is a two-character EBCDIC code that can be used by IBM® Service Personnel to determine which Catalog Management module set the reason and return code. The module identification information is not generally useful for applications.

Reason and return codes returned by Catalog Management are found in LookAt under message IDC3009I. For the description of a particular return and reason code, see z/OS MVS System Messages, Vol 6 (GOS-IEA). For Return codes 100 (X'64') and 122 (X'7A'), see Table 1
