UCBINFO PRFXDATA - Execute form

Use the execute form of the PRFXDATA option of the UCBINFO macro together with the list form of the macro for applications that require reentrant code. The execute form of the macro stores the parameters into the storage area defined by the list form.

The execute form of the PRFXDATA option of the UCBINFO macro is written as follows:

Syntax	Description

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

␢	One or more blanks must precede UCBINFO.

UCBINFO

␢	One or more blanks must follow UCBINFO.

PRFXDATA

,DEVN=`devn addr`	`devn addr`: RS-type address or register (2) - (12).

,SCHSET=`schset`	`schset` RS-type address or register (2) - (12).
,SCHSET=0	Default: 0

,UCBPTR=`ucbptr addr`	`ucbptr addr`: RS-type address or register (2) - (12). Note: Specify either DEVN or UCBPTR, but not both.

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

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

,LINKAGE=SYSTEM	Default: SYSTEM
,LINKAGE=BRANCH

,PLISTVER=IMPLIED_VERSION
,PLISTVER=MAX	Default: IMPLIED_VERSION
,PLISTVER=`plistver`	`plistver`: 2

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

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

,MF=(E,`list addr`)	`list addr`: RX-type address or address in register (2) - (12).
,MF=(E,`list addr`,COMPLETE)	Default: COMPLETE

Parameters

The parameters are explained under the standard form of UCBINFO PRFXDATA with the following exceptions:

,MF=(E,list addr)

,MF=(E,list addr,COMPLETE)

Specifies the execute form of the UCBINFO PRFXDATA macro.

list addr specifies the area that the system uses to contain the parameters.

COMPLETE, which is the default, specifies that the macro is to check for required parameters and supply defaults for omitted optional parameters.
