Exit options

The exit options field is a 4-byte field that indicates the functions for which VTAM® will call the exit routine. This field is modified by the exit routine during begin function processing. The bit definitions are described in Table 1.

Table 1. Session management exit options
Byte	Bit	Description
0	B'1... ....'	The exit routine will process the initial authorization function (function code X'00').
	B'0... ....'	The exit routine will not process the initial authorization function (function code X'00'). The default is 0.
	B'.1.. ....'	The exit routine will process the secondary authorization function (function code X'01').
	B'.0.. ....'	The exit routine will not process the secondary authorization function (function code X'01'). The default is 0.
	B'..1. ....'	The exit routine will process the initial and final accounting functions (function codes X'02' and X'03').
	B'..0. ....'	The exit routine will not process the initial and final accounting functions (function codes X'02' and X'03'). The default is 0.
	B'...1 ....'	The exit routine will process the gateway path selection function (function code X'04').
	B'...0 ....'	The exit routine will not process the gateway path selection function (function code X'04'). The default is 0.
	B'.... 1...'	The exit routine will process the end function (function code X'FF').
	B'.... 0...'	The exit routine will not process the end function (function code X'FF'). The default is 0.
	B'.... .1..'	The exit routine will process the XRF session switch function (function code X'05').
	B'.... .0..'	The exit routine will not process the XRF session switch function (function code X'05'). The default is 0.
	B'.... ..1.'	The exit routine will process the adjacent SSCP selection function (function code X'06').
	B'.... ..0.'	The exit routine will not process the adjacent SSCP selection function (function code X'06'). The default is 0.
	B'.... ...1'	Adjacent SSCP selection is allowed for DSRLST.
	B'.... ...0'	Adjacent SSCP selection is not allowed for DSRLST. The default is 0.
1	B'1... ....'	Session management exit functions are allowed for takeover of LU sessions.
	B'0... ....'	Session management exit functions are not allowed for takeover of LU sessions. The default is 0.
	B'.1.. ....'	Initial authorization is allowed for INIT OTHER CD.
	B'.0.. ....'	Initial authorization is not allowed for INIT OTHER CD. The default is 0.
	B'..1. ....'	The exit routine will process the alias selection function (function code X'07').
	B'..0. ....'	The exit routine will not process the alias selection function (function code X'07'). The default is 0.
	B'...1 ....'	The exit routine will process the ALS selection function (function code X'08').
	B'...0 ....'	The exit routine will not process the ALS selection function (function code X'08'). The default is 0.
	B'.... 1...'	ALS selection is allowed for DSRLST. For this indicator to be valid, also indicate that the exit routine will process the ALS selection function.
	B'.... 0...'	ALS selection is not allowed for DSRLST. The default is 0. For this indicator to be valid, also indicate that the exit routine will process the ALS selection function.
	B'.... .1..'	ALS selection is allowed for all CDRSCs that could possibly be an independent LU served by this SSCP. For this indicator to be valid, also indicate that the exit routine will process the ALS selection function.
	B'.... .0..'	ALS selection is allowed only when the DLU is considered to be an independent LU. The default is 0. For this indicator to be valid, also indicate that the exit routine will process the ALS selection function.
	B'.... ..1.'	The exit routine will be driven for MODIFY EXIT processing. The default is 0.
	B'.... ..0.'	The exit routine will not be driven for MODIFY EXIT processing. The default is 0.
	B'.... ...1'	The exit routine will process the virtual route selection function (function code X'0B'). The default is 0.
	B'.... ...0'	The exit routine will not process the virtual route selection function (function code X'0B'). The default is 0.
2	B'1... ....'	Session accounting exit functions are allowed for multinode persistent session recovery.
	B'0... ....'	Session accounting exit functions are not allowed for multinode persistent session recovery.
	B'.1.. ....'	The exit routine will process the HPR virtual route selection function (function code X'0C'). The default is 0.
	B'.0.. ....'	The exit routine will not process the HPR virtual route selection function (function code X'0C'). The default is 0.
