Loading and executing functions

In order to use a function, its definition must first be loaded into EASI. If the function in the previous example is defined in a file called

• USERFUNC.EAS

then the LOAD command can be used as follows:

load "USERFUNC.EAS"

After it has been loaded, the function may then be invoked using the CALL command:

call WaitForUserResponse()

The empty brackets after the function name indicate the function requires no arguments.
