I've put together several mouse and keyboard routines for SCREEN 0 over the years.

Here is one demo example...

Code: (Select All)
mydemo% = -1
DIM UI AS UserInput

TYPE UserInput
    KeyPress AS STRING
    KeyCombos AS INTEGER
    MbStatus AS INTEGER
    MbEnvoked AS INTEGER
    drag AS INTEGER
    DoubleClick AS INTEGER
    MbLeftx AS INTEGER
    MbLefty AS INTEGER
    mx AS INTEGER
    oldmx AS INTEGER
    my AS INTEGER
    oldmy AS INTEGER
END TYPE

PRINT "Press keys or use mouse for demo.";
DO
    CALL keyboard_mouse(UI, mydemo%)
    IF UI.MbStatus < 0 AND UI.MbEnvoked = 0 THEN
        SOUND 1000, .3: UI.MbEnvoked = -1
    END IF
    IF UI.KeyPress = CHR$(13) THEN BEEP: EXIT DO
LOOP

DO
    CALL keyboard_mouse(UI, mydemo%)
    IF UI.MbStatus > 0 AND UI.MbEnvoked = 0 THEN
        SOUND 300, .3: UI.MbEnvoked = 1
    END IF
LOOP

END

SUB keyboard_mouse (UI AS UserInput, mydemo%)
    STATIC z1, lclick

    _LIMIT 30

    DEF SEG = 0
    IF PEEK(1047) MOD 16 = 1 OR PEEK(1047) MOD 16 = 2 THEN
        UI.KeyCombos = 1 ' Shift = -1 ELSE Shift = 0
    ELSEIF PEEK(1047) MOD 16 = 3 OR PEEK(1047) MOD 16 = 4 THEN
