Whenever I try to use RND(3) It says that it can't understand command at line 14.


RND(3)


Thankyou

the line numbers it gives can sometimes be misleading, and there is not really enough information here, can you post a bit more of the code, before and after the rnd so we can see how exactly you're trying to use it?

Judging by your post, the command was used incorrectly.

Result = Rnd(3)

It's an expression so it must have an assignment or be a parameter.

Ahh, thanks for the reply, is it possible to use RND to print a word from the ones I have chosen. If so would this work:


RND(3)
IF RND = "3" THEN PRINT "TEST"
IF RND = "2" THEN PRINT "TEST"
IF RND = "1" THEN PRINT "TEST"
IF RND = "0" THEN PRINT "TEST"

You should probably do this though.



RND() will always return something different whenever you call it. Calling it once and storing the result in a variable (x) means that x can only be one thing.

If you used chafari's code, it'd randomly print "TEST". Maybe that's what you want though.

The above code is sufficient; but what I do is:

Print "TEST" + Str$(Rnd(3)+1)

Or

Dim Result$(3) : Result$(0) = "First" : Result$(1) = "Second"
Result$(2) = "Third" : Result$(3) = "Forth"
Print Result$( Rnd(3) )
