INTRINSIC DESCRIPTIONS
Dependency Between Intrinsics
Certain intrinsics must be called before other intrinsics can be executed. Figure 6-3.
illustrates the standard dependencies among intrinsics. For example, the terminal file
must be opened before any other intrinsics are called if prompts are to be sent to the
terminal. Each of the three files, terminal, forms and batch must be opened before
operations can be performed on these files and before the files can be closed.
