IKJTSOEV supports five optional parameters. The parameters are positional and follow standard parameter passing conventions (see z/Architecture® Principles of Operation). In assembler language, the high-order bit of the last specified parameter must be set to 1 to indicate the end of the parameter list. If no parameters are specified, register 1 should be set to 0.

parm1

A fullword which is reserved for future use.

parm2

A fullword integer. Upon return from IKJTSOEV, this parameter contains a return code indicating the completion status of the call. For more information on this parameter, see Table 1.

parm3

A fullword integer. Upon return from IKJTSOEV, this parameter contains a reason code that provides specific information about an unsuccessful completion. For more information on this parameter, see Table 2 and Table 3.

parm4

A fullword integer. Upon return from IKJTSOEV, this parameter contains a code that further describes an error indicated in parameter 3. For more information on this parameter, see Table 3.

parm5

A fullword address. Upon return from IKJTSOEV, this parameter contains the address of the Command Processor parameter list (CPPL). For more information on the Command Processor parameter list, see Interfacing with the TSO/E service routines.
