This should be right. Now you can make those fast Hexadecimals in your program..
Its ready to compile and then you can execute it, and resize the window and place it where you want for quick conversion..
Code:
10 PRINT
20 PRINT "Enter a number "
30 INPUT number
40 PRINT "The hexadecimal is :"
50 PRINT "&"+STR$~(number)
60 PRINT "Press ENTER to clear the screen and convert more"
70 INPUT A$
80 CLS
90 GOTO 10
