===== EXTERNAL INTEGRATION SYSTEM CALLS (ON COMMODORE 64) =====

==== PURPOSE ====
 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.  

==== SOURCE CODE ====
   
   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
