'Ascii Code Utility By Jeff Shantz
'
'Programmer's Note
'
'This Utility Was Programmed In About 2 Minutes.  I Just Sat Down And Thought
'That It Would Be Nice To Make A Program That Shows User's Some Of The
'Commands In QuickBasic That Aren't Used Everyday.  This Program Uses
'3 Main Commands, STRING$, INKEY$ And ASC.  Many Programmers In QuickBasic
'Who Are Moderately Good Actually Do Not Know Those Three Commands.  They
'Are Quite Useful As INKEY$ And ASC Can Be Used To Make Programs With
'Hotkeys Etc. 
'
CLS
N = 1                 'sets the variable used to determine the ascii code to 1
1 FOR I = 1 TO 999999 'start the loop
LOCATE 1, 1           'locates the coordinates 1,1 on the screen
X$ = STRING$(1, N)    'sets the ascii code currently being displayed to X$

'The Following Will Set It So That The Program Acts Upon A Keypress
A$ = INKEY$: IF LEN(A$) = 0 THEN 2

'the statement below sets it so that if [ is pressed, N is lowered by 1
IF ASC(A$) = 91 THEN N = N - 1
'the statement below sets it so that if ] is pressed, N is raised by 1
IF ASC(A$) = 93 THEN N = N + 1 ELSE N = N 'stays same if other keys pressed
IF ASC(A$) = 27 THEN 3 'if escape is pressed, the program ends
IF N = -1 THEN N = N + 1: GOTO 1 'makes it so that you can't go below 0
IF N = 256 THEN N = N - 1: GOTO 1 'makes it so that you can't go above 255
2 NEXT I
3 SYSTEM 'exits to dos when run from DOS, otherwise just ends the program.
