SYNCH and SYNCHX - Execute form

z/OS MVS Programming: Authorized Assembler Services Reference SET-WTO
SA23-1375-00

The execute form of the SYNCH or SYNCHX macro uses a remote program parameter list that can be generated by the list form of SYNCH or SYNCHX.

Syntax

The execute form of the macro is written as follows:

Syntax	Description

`name`	`name`: Symbol. Begin `name` in column 1.

␢	One or more blanks must precede SYNCH or SYNCHX.

SYNCH

␢	One or more blanks must follow SYNCH or SYNCHX.

`entry point addr`	`entry point addr`: RX-type address, or register (2) - (12) or (15).

,RESTORE=NO
,RESTORE=YES

,KEYADDR=`addr`	`addr`: RX-type address, or register (2) - (12).
,KEYADDR=NOKEYADDR

,STATE=PROB
,STATE=SUPV

,KEYMASK=`addr`	`addr`: RX-type address, or register (0) - (12).
,XMENV=`addr`	`addr`: RX-type address or register (0) - (12).

,AMODE=24	Note: AMODE=DEFINED can only be specified if the entry point is provided in a register.
,AMODE=31
,AMODE=DEFINED
,AMODE=CALLER

,MF=(E,`ctrl addr`)	`ctrl addr`: RX-type address or register (1), (2) - (12).

Parameters

The parameters are explained under the standard form of the SYNCH macro with the following exceptions:

,KEYADDR=NOKEYADDR: Indicates that the default(the key in the TCB) should be used instead of the key in the parameter list defined by a list form of the macro.
,MF=(E,ctrl addr): Specifies the execute form of the SYNCH macro using a list generated by the list form of SYNCH.

Example

Use the execute form of the SYNCH macro to take a synchronous exit to the program located at the address given in register 8 and restore registers 2-13 when control returns. Indicate that the program is to receive control in the same addressing mode as the caller and that the parameter list is located at SYNCHL2.
