This small example explains how to invoke Commodore 64 system functionalities. Please note that this is only an example, and that you need to have a good understanding of how the KERNAL and BASIC works in order to use this functionality. In order for this example to work, it needs access to the import file invoked in the first line (IMPORT DECLARES). The file is located in the “/imports” folder, and is downloaded automatically by the IDE from version 1.14.1 onwards.
IMPORT DECLARES CLS PRINT "---------------------------------------" PRINT "--- ugBASIC : SYS EXAMPLE C64" PRINT "---------------------------------------" PRINT "This example will work only " PRINT " under Commodore 64" PROCEDURE example ON C64 PRINT "Press any key..." DO scnkey[] c = getin[] IF c <> 0 THEN PRINT "(key pressed!)" ENDIF LOOP END PROC example[] ON C64
