POKER seems perfectly adequate to handle this task and the user can handle sprite magnification when the screen is enabled:

CALL POKER(1,-32) = enable screen and CALL MAGNIFY(1)

CALL POKER(1,-31) = enable screen and CALL MAGNIFY(2)

CALL POKER(1,-30) = enable screen and CALL MAGNIFY(3)

CALL POKER(1,-29) = enable screen and CALL MAGNIFY(4)

 

 

Similarly, with XB256, after disabling the limit check with CALL LOAD(14864,128), you would use these values:

CALL LINK("SCREEN",-1327) = enable screen and CALL MAGNIFY(1)

CALL LINK("SCREEN",-1326) = enable screen and CALL MAGNIFY(2)

CALL LINK("SCREEN",-1325) = enable screen and CALL MAGNIFY(3)

CALL LINK("SCREEN",-1324) = enable screen and CALL MAGNIFY(4)

 

You disable the screen with CALL LINK("SCREEN",-1391)
