SAS(R) 9.1.3 Companion for z/OS

Statements under z/OS FILE Statement 367
SAS assigns values to the variables that are defined by these options when it opens the
data set. It updates the values every time it opens a new data set in a concatenation.
You can use these options with all standard external files under z/OS.
DEVTYPE=variable
defines a character variable (minimum length 24) that SAS sets to the device type.
SAS obtains the device type by using the z/OS operating environment DEVTYPE
macro. For more information, see the IBM documentation for your operating
environment.
DSCB=variable
defines a character variable (minimum length 96) that SAS sets to the Data Set
Control Block (DSCB) information from a non-VSAM data set. For more
information, see the IBM documentation for your operating environment.
JFCB=variable
defines a character variable (minimum length 176) that SAS sets to the Job File
Control Block (JFCB). For more information, see the IBM documentation for your
operating environment.
UCBNAME=variable
defines a character variable (minimum length 3) that SAS sets to the unit name
(device address), which is derived from information in the unit control block (UCB).
VOLUME=variable | VOLUMES=variable
defines a character variable (with a minimum length of 6 characters) that SAS
sets to the tape VOLSER or the disk volume serial number. In the case of a
multivolume file, the VOLUME= variable contains the concatenated volume serial
numbers up to the length of the variable or the first 30 volumes, whichever is less.
The value in the VOLUME= variable contains the volume serial number of the
first data set in the concatenation when the file is opened. This serial number
changes if you open a subsequent data set in the concatenation.
VSAM Options for the FILE and INFILE Statements under z/OS
You can use the following options for VSAM files in the FILE statement and in the
INFILE statement. (Unless otherwise indicated, the option can be used in both.)
BACKWARD | BKWD
causes SAS to read the VSAM data set backwards (INFILE only).
BUFND=value
indicates how many data buffers to use for the VSAM data set.
BUFNI=value
indicates how many index buffers to use for the VSAM data set.
CONTROLINTERVAL | CTLINTV | CNV
indicates that you want to read physical VSAM control interval records rather
than logical records. This is typically used for diagnostic purposes (INFILE only).
ERASE=variable
defines a numeric SAS variable that you must set to 1 when you want to erase a
VSAM record (INFILE only).
FEEDBACK=variable | FDBK=variable
defines a numeric variable that SAS sets to the VSAM logical error code. This is
similar to the _FDBK_ automatic variable. When SAS sets the FEEDBACK
variable, you must reset it to 0 in order to continue.
GENKEY
causes SAS to use the KEY= variable as the leading portion of a record’s key.
VSAM retrieves the first record whose key matches the generic key (INFILE only).
