    Please don't post OS specific code as an answer to a generic C question. I can't even compile your code on my OS, and I have a Borland compiler!
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]

    Actually, this is wrong. This would only give you 60 to 99.

    var = 60 + rand()%41;

    Also, just see the FAQ (original poster) for using random numbers.

    Because the little ones are the hardest to see.
