AB The call did not specify a segment I/O area. This is a programming error.
AC The call included an SSA with a hierarchical error. This is a programming error.
(all get calls and ISRT)
AD The key field specified for the call contains an incorrect value. Programming error.
AH The call requires at least one SSA. Programming error.
AI An error occurred when trying to open the data base data set.
It could be due to an error in the JCL. Or trying to load an already existing data base or processing on an empty data base.
AJ The call specifies an invalid SSA. A programming error. The PCB?s segment level field contains the level number of the segment for which the SSA is invalid. For an ISRT call, the lowest level SSA must be unqualified. For a REPL call, there may not be a qualified SSA. And for a DLET call, there may be only one SSA and it must be unqualified.
AK The field that is uses in a qualified SSA is not correct. A programming error.
Calls: All get calls and ISRT
AM The call attempted an unauthorized operation. An operation not allowed by the processing options or sensitive segments specified in the PCB. A programming error.
