Return codes

Table 1 lists the return codes issued by the external routine search routine.

Table 1. Return codes from the external routine search routine
Return code (decimal)	Description
0	Processing was successful. IRXERS located the external routine, and the external routine returned control with a return code of 0 in register 15. If EXTFCT or EXTBRFCT was specified, the address of the EVALBLOK is available in parameter 5.
4	Processing was successful. IRXERS located the external routine, and the external routine returned control with a return code of 0 in register 15. However, EXTFCT or EXTBRFCT was specified, and no EVALBLOK was returned by the external routine.
8	Processing was successful. IRXERS located the external routine, and the external routine returned with a non-zero return code in register 15.
12	Processing was not successful. IRXERS attempted to create an EVALBLOK, but insufficient virtual storage was available.
16	Processing was not successful. IRXERS could not locate the specified routine.
20	Processing was not successful. An error message may accompany this return code.
28	Processing was not successful. IRXERS was unable to locate a language processor environment. Verify that you passed a valid environment block address.
32	Processing was not successful. The parameter list is not valid. The parameter list contains either too few or too many parameters, or the high-order bit of the last address in the list is not set to 1 to indicate the end of the parameter list.
100	Processing was not successful. IRXERS located and passed control to the external routine. However, an abend occurred in the external routine.
