Here's my very basic code dealing with the random number generator. I want it so that when the user inputs break or Break the app will jump to label 2 and then end itself. However, all it does is add a random number to the end of Break. Also, the random number generator appears to only create a random number > .0. Any ideas?

Here's my code:

Label 1
randomize 1
input A
if A=Break|break then goto 2
A=A+RND
print A
goto 1

label 2
end

| means "or"

INPUT A
PRINT A,Break,break

RUN see what you get, guessing 0,0,0.

Find out what your dealing with. Suspect Break=0 as a default setting for initialising the variable. It'll be an ASCII(4 maybe EOD) value or more likely default to zero again if not set. You've got the whole INKEY or KEY and build your own input emulator if it won't tell you Break. Better way is $ input and check ="" or else EVAL.

In most basics with a fractional RND.
num=((13-6)*RND)+6
to get 6<= num <13 results

INPUT A
PRINT A,Break,break


returns: 0 0

So you hit break on the INPUT a and it returned nothing. Haven't seen behaviour like that since the Sinclair QL automatic string-numer thing which had a very technical term.

Can you
INPUT A
IF(A="") PRINT "Batman"

See if it spits on the "".

I had to add a "then" to it otherwise it refused to let the PRINT come on the same line after the IF.


Here:

INPUT A
IF A="" THEN PRINT "Batman"

Returns: Batman
