Continue by hitting a certain key

I dont get it, lol.

Me neither.

C'mon people.

GOTO = instruction
HELL = destination

Programmers think GOTO is worse than HELL.

You should use a library. Unless you enjoy POUNDING on your keyboard.

:lol:

And sorry to kill this thread with the all-encompassing answer, but:

Code:

numofkeystocheck% = 4   ' Set to the number of keys in the array you wish to check for
DIM keys(1 TO numofkeystocheck%) AS STRING * 1

' Insert the scancodes you wanna check for here
keys(1) = CHR$(27)
keys(2) = CHR$(13)
keys(3) = CHR$(32)
keys(4) = CHR$(65)

' The loop
DO
  K$ = ""
  DO
    K$ = INKEY$
  LOOP UNTIL K$ <> ""
  FOR I = 1 TO numofkeystocheck%
    IF K$ = keys(I) THEN EXIT DO
  NEXT I
LOOP

PRINT "You pressed a key in the array, index number"; I

He used EXIT DO, see?

Exit do works fine, but I've been programming for ages now, and I have never encounted problems with GOTO. What is wrong with it?

A modification of Oracle's code

Code:

'Choices are Esc, Enter, Space, and A
Choice$ = CHR$(27) + CHR$(13) + CHR$(32) + CHR$(65)

' The loop
DO
  DO
    K$ = INKEY$
  LOOP UNTIL K$ <> ""
LOOP WHILE INSTR(Choice$, K$) = 0

SELECT CASE K$
  CASE CHR$($27)
    K$ = "Esc"
  CASE CHR$($13)
    K$ = "Enter"
  CASE CHR$($32)
    K$ = "Space"
  CASE ELSE  
END SELECT

PRINT "You pressed an available key: "; K$

The loop is more concise. The code after the loop is longer, but it is like what you will often use in a program.

In previous projects they have hammered me for using the goto command. And, in some sense for people it is bad because they don't ever compact their modules. When you get to humungus programs, that GOTO space gets removed or you can't expand anymore. But, I found it really usefull when trying to create certain text games where you must return to a specific place, and in fact I still use it. Its alot easier to comprehend than all those loops and dim thingys. :bounce: :bounce: :bounce: :bounce: :bounce: :bounce: :bounce: :bounce: :bounce: :bounce: :bounce: :bounce: :bounce: :lol:

Andy,
The careful use of GOTO's is okay, but they make the code much harder to follow than using loops and subs. As a result it is much harder to debug.

Terry,
You find loops and arrays ("those dim thingys') hard to understand because you haven't learned to use them. Once you do you will find that they make programming much easier. among other things, they save you having to write the same code over and over again.

Ah, but my code loops around again if the user doesn't press an available key
