- assigns or deassigns a libref for a SAS
data library and returns a value.
- LIBREF
- verifies that a libref has been assigned
and returns a value.
- MOPEN
- opens a file by directory ID and by member
name and returns either the file identifier or a zero (0).
- PATHNAME
- returns the physical name of a SAS data
library or of an external file or returns a blank.
- SYSGET
- returns the value of a specified operating-environment
variable.
The following SAS informat has been enhanced:
- $HEXw.
- converts hexadecimal data to character data.
The width range has increased.
The following SAS procedure has been changed:
- PMENU
- defines pull-down menu facilities for windows
that were created with SAS software. OpenVMS does
not support the ACCELERATE= and MNEMONIC= options
in the ITEM statement or the ATTR= and COLOR= options
in the TEXT statements.
The following SAS procedure is no longer supported:
The following SAS statements have been changed or enhanced:
- ATTRIB
- associates a format, informat, label, length,
or any combination of these items with one or more variables. The minimum
length that you can specify has changed.

- specifies the current output file for PUT
statements. GSFCC=, KEY=, and KEYVALUE= were
added as valid values for the host-option-list
argument. BLKSIZE= is no longer supported
as a value for the host-option-list argument.
In
Version 8, a new valid device type, PIPE, has been added.
- FILENAME
- associates a SAS fileref with an external
file. GSFCC= was added as a valid value
for the host-option-list argument. BLKSIZE=
| BLK= is no longer supported as a value for the host-option-list
argument.
In
Version 8, a new valid device type, PIPE, has been added. In addition, for
Version 8, you can specify a file version to write to.
- INFILE
- specifies an external file to read with an INPUT statement.
In Version 8, a new valid device type, PIPE, has been added.
