PartRestoreScreen                                               WinTTT



Purpose   To restore a portion of a saved screen to the display.

Declaration    PartRestoreScreen(Page,X1,Y1,X2,Y2,X,Y: integer);

          Page is the number of the saved screen
          X1 is the top left X coord of saved screen (1..80)
          Y1 is the top left Y coord of saved screen  (1..25)
          X2 is the lower X coord of saved screen (1..80)
          Y2 is the lower Y coord of saved screen (1..25)
          X is the top left X coord of the target location (1..80)
          Y is the top left Y coord of the target location (1..25)

Uses CRT, FastTTT, DOS, WinTTT.

Remarks   The procedure is used to restore part of a screen that was
          previously saved with SaveScreen. The first four coord.
          parameters indicate which part of the saved screen should be
          restored, and the last pair of coords indicate the position
          on the screen where the top left corner of the restored data
          is located.

Example


               USES CRT, FASTTTT, DOS, WINTTT;
               BEGIN
                 SAVESCREEN(1);
                 .....
                 ..    {SCREEN MODIFYING PROCEDURES}
                 .....
                 PARTRESTORESCREEN(1,1,1,80,12,1,13);
                 DISPOSESCREEN(1);
               END.


In this example, the screen is saved (let's assume there was something
meaningful on the screen at that point), then some other procedures
modify the screen display. The top half of the saved screen is then
restored to the lower half of the screen display.
