Return and Reason Codes

When the system returns control to the caller, GPR 15 (and retcode, if you coded RETCODE) contains the return code and GPR 0 (and rsncode, if you coded RSNCODE) contains the reason code.

Table 1. Return and Reason Codes for the IHABLDP Macro
Hexadecimal Return Code	Hexadecimal Reason Code	Meaning and Action
00	None	Meaning: IHABLDP completed successfully. Action: None
08	04	Meaning: There is insufficient space in the dump parameter list to add the requested entry. Action: Ensure that you have correctly calculated the amount of storage required for the STRLIST parameter list.
08	08	Meaning: The range entry was not added to the dump parameter list because the starting range value was greater than the ending range value. Action: Verify that you specified the correct starting and ending range values on the TYPE=STRRNG request.
