Routine Description:

    This routine parses multi-strings of the form

        "foo" "bar" "bletch"

    Each time it is called, it strips the first string in quotes from
    the input string, and returns it as the multi-string.

    INPUT ValueString: "foo" "bar" "bletch"

    OUTPUT ValueString: "bar" "bletch"
           ValueData: foo

Arguments:

    BackwardsCompatibleInput - TRUE if supporting old format input

    ValueString - Supplies the string from which the multi-string will be
                  parsed
                - Returns the remaining string after the multi-string is
                  removed

    ValueData - Supplies the location where the removed multi-string is
                to be stored.
              - Returns the location to the first byte after the returned
                multi-string

    MaximumValueLength - Supplies the maximum length of data that can be
                         stored in ValueData.

    ValueLength - Supplies a pointer to the current length of data stored
                  in ValueData.
                - Returns the size of the


Return Value:

    TRUE if successful and FALSE if not.
