UCBSCAN COPY - List form

Use the list form of the UCBSCAN macro together with the execute form for applications that require reentrant code. The list form of the macro defines an area of storage that the execute form uses for storing the parameters.

Syntax

This macro is an alternative list form macro, and requires a different technique for using the list form as compared to the conventional list form macros. See Alternative list form macros for further information.

The list form of the COPY function of the UCBSCAN macro is written as follows:

Syntax	Description

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

␢	One or more blanks must precede UCBSCAN.

UCBSCAN

␢	One or more blanks must follow UCBSCAN.

,PLISTVER=IMPLIED_VERSION
,PLISTVER=MAX	Default: IMPLIED_VERSION
,PLISTVER=`plistver`	`plistver:` 1

MF=(L,`list addr`)	`list addr:` Symbol.
MF=(L,`list addr`,`attr`)	`attr`: 1- to 60-character input string.
MF=(L,`list addr`,0D)	Default: 0D

Parameters

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

MF=(L,list addr)

MF=(L,list addr,attr)

MF=(L,list addr,0D)

Specifies the list form of the UCBSCAN macro.

The list addr parameter specifies the address of the storage area for the parameter list.

attr is an optional 1- to 60-character input string, which can contain any value that is valid on an assembler DS pseudo-op. You can use this parameter to force boundary alignment of the parameter list. If you do not code attr, the system provides a value of 0D, which forces the parameter list to a doubleword boundary.
