Functions An HP ALLBASE/4GL function is similar to a subroutine in a conventional language. When HP ALLBASE/4GL finishes executing a function, it resumes running the application at the point where the function was initiated. Functions may be nested. That is, one function may call another function. The maximum depth of nesting is 99, and recursion is permitted. Creating a function also involves completing a function header screen and a function detail screen. The function logic block defined in the function detail screen is similar to a process logic block.
