Although there is a large class of procedures that are totally self-contained, most procedures require some input data and return some data to the caller. Parameters are values that you pass to and from a procedure. In straight assembly language, passing parameters can be a real chore. Fortunately, HLA provides a high level language–like syntax for procedure declarations and for procedure calls involving parameters. This section will present HLA's high level parameter syntax. Later sections in this chapter will deal with the low level mechanisms for passing parameters in pure assembly code.
The first thing to consider when discussing parameters is how we pass them to a procedure. If you are familiar with Pascal or C/C++, you've ...
