general.screen

utilities to display formatted menus.
The screen utility consists of a series of PICK/BASIC subroutines to handle formatted menus. All data is passed between the subroutines and the main program through a COMMON defined in the include 'dm,bp,includes, screen.inc'. The routines are described in more detail in the appropriate Reference Manual section.

screen.init Initialize the COMMON. This routine must be called before any other routine is called. After calling it, the main program may modify some the COMMON variables.

screen.display Display a screen and wait for a menu selection.

screen.input Display an input screen and wait for user data to be input.

screen.erase Erase a screen section.
