This topic contains:
- An overview of the concepts of the Graphical Kernel System (GKS)
- An introduction to some of the GKS functions
- A step-by-step analysis of the ROOM program.
Notes:
1. GKS is a standard having several different levels, each higher level
providing more functions. In this topic, the term GKS is used when
generic GKS functions are discussed, but the term GDDM-GKS is used
when the functions provided specifically by this implementation of GKS
are described.
2. In this topic, programming examples are given in a generic, pseudocode
format. Function calls use the GKS function names, rather than the
FORTRAN binding names, to make the purpose of the example clearer. If
you wish to code one of the examples, you will need to substitute
calls to the binding names, given in "GDDM-GKS functions" in
topic 5.0.
