    The '&H' prefix allows you to code hexadecimal numbers directly.

    William,

    This is a number expressed in hexidecimal. The &H denotes hex, while
    &O denotes octyl. &H18F = 399 in this case. Each character after &H can
    range from 0 to F (equivalent to 0 to 15). from right to left the value
    is multiplied by 16^(position-1), so in your number 1 = 1 * 16^(3-1) or 256,
    8 = 8 * 16^(2-1) or 128 and finally F = 15 * 16^(1-1) or 15. Summing these
    values gives us 399. An easy way to convert is typing ? &H18F in the immediate
    window, the result will be 399. Hope this helps.

    Chris
