Can someone explain to me what the ampersand represents in this declaration: ByVal sigNode& as well as the dollar sign and percent for variables: szEntity$, ret %.

    got this from Q_20343884

    The "$" is a carryover from the original BASIC to indicate that a variable or function was a string-type.  In VB, this was retained and later made optional, although the string-type operates slightly faster than the version without the string (which uses a variant.)

    If you attempt to use a "$" after a non-string variable, you may get an error.

    These are identical in VB6:

    Dim A$
    Dim A as string

    and i just found the rest

    they are all type declaration indicators -

    ($) - string
    (!) - single
    (&) - long
    (%) - integer
    (#) - double
    (@) - currency

    So, if these are optional as long as I find replace them and properly declare the values correctly I shouldn't have any problems?

    exactly, i think they kept them in for the "smooth transition" effect for BASIC to vb users.  

    they took them out in vb.net....
