I'm having a problem with the random() function in BrickOS.  I keep getting a
return value of zero.

Is there something that needs to be set-up before using the function?

What kind of value does it return?  I've seen documentation that says it returns
a value between MIN_INT and MAX_INT, and another that says place it says it
returns a number up to RAND_MAX.

I'm just using a function like:

int column;
column = random();

Thanks
Steve

(...) I found out what my problem was. I didn't seed the random number. This seems to be REQUIRED. (21 years ago, 30-Dec-03, to lugnet.robotics.rcx.legos)
