Routine Description:

    Thie function is use together with the Assert MACRO.
    It checks to see if an expression is FALSE.  if the

Arguments:

    Expression  - The text of the 'C' expression
    File        - The file that caused the assertion
    LineNumber  - The line number in the file.

Return Value:
