Note: these can be used only under IDCAMS and not from the
TSO prompt.

IF LASTCC(or MAXCC) >(or <,= etc..) value -

THEN -

DO -

command set (such as DELETE, DEFINE etc..)

ELSE -

DO -

command set

LASTCC - Condition code from the last function (such as
delete) executed

MAXCC - Max condition code that was returned by any of the
prev functions

SET is also a valid AMS command. SET LASTCC (or MAXCC) = value

The maximum condition code is 16. A cond code of 4 indicates
a warning. A cond code of 8 is usually encountered on a
DELETE of a dataset that is not present.
