Timer()

         Lets you define the number of ticks per second.

    Syntax:

         Timer( nTicks ) -> Nil

         nTicks : Number of ticks per second

    Description:

         With this functions you program the timer 0 to produce the ticks per
         second specified.
         The larger this value is the more number of interrupts per second
         (the system will go slower).
         However, if we set small value, the system will go faster.

         WARNING!!
         To set the frecuence to the default value, the parameter nTicks must
         be set to 0.

    Return:

         Nothing.

    Example:

         Timer( 5 )
         Timer( 100000 )
