SAS Data Location Assist
for
z/OS (zDLA) enables you
to use the flexibility of the SAS DATA step to gather information
about attributes for data sets that reside throughout your operating
system. You can use zDLA to retrieve information about all forms of
z/OS data sets, including sequential,
VSAM, partitioned, and UFS files. zDLA enables you to process the
types of attribute information that are obtained from other utility
programs without writing lengthy SAS DATA steps. It also eliminates
the need for you to use multiple utilities to retrieve this information,
or the need to write additional utilities in the Assembler language.
zDLA provides the following
SAS functions that you can use to retrieve information about data
set attributes:
| ZVOLLIST |
returns a list of volume serial numbers. |
| ZDSLIST |
returns a list of data set names. |
| ZDSNUM |
returns a count of the number of data set names
previously returned from the ZDSLIST function.
|
| ZDSIDNM |
returns individual data set names from the variable
created by function ZDSLIST, based on an index.
|
| ZDSATTR |
returns the attributes for the data set name that
is specified in the input variable, according to the type of request.
|
| ZDSXATT |
returns the number of attributes relevant to a given
request to a numeric variable.
|
| ZDSYATT |
returns attributes relevant to a given request. |
