Formal File Designators
HP ALLBASE/4GL can receive inputs from a number of different sources, and
direct output to a number of different destinations. The following table
lists the formal file designators for the sources of inputs and the
output destinations, the default devices, and the corresponding formal
file designators. Each of these files can be equated using an MPE/iX
file equation.
