Function codes for logical and physical errors

When a logical or physical error occurs during processing that involves alternate indexes, VSAM provides a code in the RPLCMPON field that indicates whether the base cluster, its alternate index, or its upgrade set was being processed and whether upgrading was satisfactory or may have been incorrect because of the error (see Table 1).

Table 1. Function codes for logical and physical errors. Function codes for logical and physical errors
Code	What was being processed	Status of upgrading
0(X'00')	Base cluster	Satisfactory.
1(X'01')	Base cluster	Might be incorrect.
2(X'02')	Alternate index	Satisfactory.
3(X'03')	Alternate index	Might be incorrect.
4(X'04')	Upgrade set	Satisfactory.
5(X'05')	Upgrade set	Might be incorrect.
