SAS Companion for the OpenVMS Operating Environment

SAS Functions under OpenVMS

A SAS function returns a value from a computation or system operation. Most functions use arguments that are supplied by the user as input.

Most SAS functions are completely described in SAS Language Reference: Dictionary. The functions that are described here have syntax or behavior that is specific to the OpenVMS operating environment.

Using Terminal-Access Functions

In the following sections, a category is listed immediately following the name and short description of each function. Most of these categories are self-explanatory. For terminal-access functions, which enable you to get information from and write information to the terminal, please observe the following caution:

CAUTION:: Do not use the terminal-access functions in the windowing environment. Terminal-access functions work in the windowing environment, but they can either overwrite the display or be overwritten by the display. (The REFRESH (CTRL-R) command can be used to restore your display.) For details about the REFRESH command, see the SAS online Help.

Under OpenVMS, the following SAS functions are terminal-access functions:
