HP ALLBASE/4GL Developer Self-Paced Training Guide

How Does HP ALLBASE/4GL Work? 

HP ALLBASE/4GL is an advanced fourth-generation programming language.  It
enables you to design and implement application software by defining the
required results, rather than defining the procedures necessary to
achieve those results.

You can develop new applications, modify existing applications, and
produce multiple versions of existing applications without having to
develop the lines of code required for those applications.

HP ALLBASE/4GL consists of menus and screens which act as templates
on which you input your application requirements such as field
specifications and record layouts.  HP ALLBASE/4GL then creates the
application functions and screens for you.

Function key labels are included at the bottom of every screen.  Each
label corresponds to a function key located along the top row of your
keyboard.

Function keys make it easier for you to move around within HP
ALLBASE/4GL. They include function keys that access the system, keys that
let you move from screen to screen, and keys that help you work with the
various screens used to develop an application.  You also can create
function keys for use by the application's end user.

Shown below is a sample HP ALLBASE/4GL screen.  This is a menu screen
that lists some of the various categories of screens available to you as
developer.  At the bottom of the screen are the function keys that can be
used with this screen.  Note that the  System Keys  function key leads
you to additional function keys.  For a thorough discussion of function
keys used in HP ALLBASE/4GL, refer to your HP Developer Reference Manual.
