UCBINFO PATHMAP - List form

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

Use the list form of the PATHMAP option of the UCBINFO 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 to contain the parameters.

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 PATHMAP 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.
   
    ,PLISTVER=IMPLIED_VERSION  
    ,PLISTVER=MAX Default: IMPLIED_VERSION
    ,PLISTVER=plistver plistver: 2
   
MF=(L,list addr) list addr: RX-type address
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 the standard form of UCBINFO PATHMAP with the following exceptions:

MF=(L,list addr)
MF=(L,list addr,attr)
MF=(L,list addr,0D)
Specifies the list form of the UCBINFO PATHMAP macro.

list addr is the name of a storage area to contain the parameters.

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.
