_iDisable()

         Inhibits the mascarable interrupts

    Syntax:

         _iDisable() -> Nil

    Description:

         Inhibits the mascarable interrupts and that makes the VMM of
         CA-Clipper not to use the dead times to make it's work.
         Is very useful when the response time of a process is fundamental
         and we do not want the VMM to use the falses dead times.
         Remember that any interrupt can be used if you do not call the
         function _iEnable().

    Return:

         Nothing.

    Example:

         _iDisable()
         For nInd := 1 To 100
           NullFunc()               // in this procces the VMM is stop
         Next
         _iEnable()
