Subset pointer status codes
If you make an error in a qualification statement that contains subset pointer options, IMS can return these status codes to your program.
- AJ
- The qualification statement used a GETFIRST, SET, SETZERO, SETCOND, or MOVENEXT option for a
segment for which there are no subset pointers defined in the DBD.
The subset options included in the qualification statement are in conflict; for example, if one qualification statement contained a SET option and a SETZERO option for the same subset pointer, IMS would return an AJ status code. S means to set the pointer to current position; Z means to set the pointer to zero. You cannot use these options together in one qualification statement.
The qualification statement included more than one GETFIRST option.
The pointer number following a subset pointer option is invalid. You either did not include a number, or included an invalid character. The number following the option must be between 1 and 8, inclusive.
- AM
- The subset pointer referenced in the qualification
statement was not specified in the program's PSB. For example, if your program's PSB specifies that
your program can use subset pointers 1 and 4, and your qualification statement referenced subset
pointer 5, IMS would return an AM status code to your program.
Your program tried to use an option that updates the pointer (SET, SETCOND, or MOVENEXT) but the program's PSB did not specify pointer update sensitivity.
Your program attempted to open a GSAM database without specifying an IOAREA.
