Syntax error???
« Thread started on: Apr 4th, 2013, 1:05pm » |

Hello all,
I have used the following code but am not sure where I have gone wrong, the error keeps coming up with Syntax error. My aim is to allow the user to try the program again if they don't choose from the dice given.
Code:
INPUT "Choose which dice to throw, 4, 6 or 12." Choice%
CASE Choice% OF
WHEN 4 PRINT "4 sided dice thrown, score "; Dice1
WHEN 6 PRINT "6 sided dice thrown, score ";Dice2
WHEN 12 PRINT "12 sided dice thrown, score ";Dice3
WHEN <> 4 OR 6 OR 12 PRINT "ERROR"
ENDCASE

You need to replace the last of your cases with an OTHERWISE clause:
Code: INPUT "Choose which dice to throw, 4, 6 or 12." Choice%
CASE Choice% OF
WHEN 4 PRINT "4 sided dice thrown, score "; Dice1
WHEN 6 PRINT "6 sided dice thrown, score ";Dice2
WHEN 12 PRINT "12 sided dice thrown, score ";Dice3
OTHERWISE PRINT "ERROR"
ENDCASE
Richard.

The parameters to WHEN are a constant expression, just like any other constant expression. What happens if you do:
PRINT 4
PRINT 6
PRINT <> 4 OR 6 OR 12
Often the simplest way to start debugging a piece of code is to PRINT each of the parameters and see what happens.
