Use the IKJEFTSV macro to map the parameter list for IKJEFTST. This mapping macro is provided in SYS1.MACLIB. Use the TVDSECT=YES option to map the TVDSECTD DSECT, instead of obtaining storage.

IKJEFTSV TVDSECT=YES

The parameters are:

Parameter 1

IKJEFTST (and IKJEFTSI and IKJEFTSR) need to invoke TSO/E I/O services (STACK, PUTLINE, GETLINE, PUTGET). It need to tell these underlying services which environment control table (ECT) to use. You have a choice at this point which ECT these services are to use.

The first parameter is a fullword containing a pointer to the environment control table (ECT) for the current environment. The ECT address can be set to one of the following values:

• The user's current environment control table (ECT)
• A value of X'00000000'

If the ECT address is set to X'00000000', the original ECT created when your TSO/E session was initialized is used. The address of the ECT is placed in this parameter on return to the caller.

Parameter 2

The second parameter is a reserved fullword. Although this parameter is not used, it must contain X'00000000'.

Parameter 3

The third parameter is a token consisting of four fullwords that identifies the TSO/E command/program invocation platform. This token must identify a command/program invocation platform that exists on the current task.

Parameter 4

The fourth parameter is a fullword containing an error code if IKJEFTST completes unsuccessfully.

All following parameters are optional. Note that the high-order bit of the address of the last parameter used must be on to indicate the end of the parameter list.

Parameter 5

The fifth parameter optional. It is a fullword containing the abend code returned from IKJEFTST to the application program when IKJEFTST terminates abnormally.

Parameter 6

The sixth parameter is optional. It is a fullword containing the reason code returned from IKJEFTST to the application program when IKJEFTST terminates abnormally.
