Syntax of AMS modal commands ?
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.
