.TFCOND          Toggle False Conditional Listing              MASM Directive

  .TFCOND

    Toggles the listing or nonlisting of false-conditional blocks
    (conditional statements whose IF expression is false), determined by
    whether or not the /X command line switch is specified.

       Notes:     If /X is specified on the command line, .TFCOND
                  suppresses false-conditional listings initially;
                  otherwise, .TFCOND enables false-conditional listings
                  initially. Subsequent .TFCOND directives reverse the
                  current status of this switch.
