PURPC)SE
The purpose of this module is to present the
user with several options for the use of some OKS
primitives. such as OPEN_WS and CLOSE_WSw
INPUTS
This program uses as inputs numhers from the
keyboard. The valid inputs to the program are ones
requested by the menu driver (1-3).
The program
also uses external files to read the re9uired
option information.
*
-jl.
.li-

The outputs of thjs program are the text
that is stored in the external files and the data
passed to the OKS routines as arguments.

The pr09ram first displays a menu giving
the user several options. Some of these options
include the explanation of several GKS primitjves
The program opens external files and reads their
information. This program does its own error
checking and recovery.
