Syntax
Parameter Values
- record-length
-
must be a nonnegative
integer up to five digits long (0...99999). GSFLEN= specifies the
length of the records written by the driver to a GSF or to the device.
If GSFLEN is 0,
SAS/GRAPH
uses the sixth byte of the PROMPTCHARS string to determine the length
of the records. If the sixth byte of the PROMPTCHARS string is 00,
the device driver sets the record length.
If you specify GACCESS=SASGAFIX
and omit GSFLEN=,
SAS/GRAPH uses the default length for the device.
Some values of the
GPROTOCOL device parameter cause each byte in the data stream to be
expanded to two bytes. This expansion is done after the length of
the record is set by GSFLEN. If you are specifying a value for GPROTOCOL
that does this (for example, SASGPHEX, SASGPLCL, or SASGPAGL), specify
a value for GSFLEN that is half of the actual record length desired.
For example, a value of 64 produces a 128-byte record after expansion
by the GPROTOCOL module.
