- Syntax Conventions -
     ------------------------------------------------------------------------

     The follow are the syntax conventions used throughout the PROCLIP2
     documentation.

   [...]     Indicates an optional parameter.  Any parameter surrounded by
               square brackets should be considered optional.  All optional
               parameters have a default.

     '...'   Indicates a parameter string.  A parameter string is a word or
               phrase used to inform the function of a certain request, as in
               'on' or 'off'.  All examples use lower case but case is not
               sensitive in any of the PROCLIP2 functions which use a
               parameter string.

      |       Indicates an exclusive or.  In other words, multiple
               parameters separated by the | character are mutually exclusive
               and cannot be used in the same function call, as in 'on' |
               'off'.

      Example:

     As this function employs all syntax possibilities, it is the best to
     discuss in an example.

               cursor(['std' | 'off' | 'half' | 'full'] | [start,end])

     [...]    The parameters surrounded by square brackets are optional in
               that they are not necessary for the function to operate in
               default mode.  When two or more parameters are enclosed within
               the same bracket pair they are dependent upon each other in
               one way or another.

      'std'  This, and the other parameters specified in this fashion, are
               string parameters informing the function of the action to
               take.  This mechanism makes reading the resulting source code
               easier as no "cryptic" codes need to be interpreted.

     |         All parameters separated by the "|" character are mutually
               exclusive in that they cannot be used in the same function
               call.  Notice how all of the "pre-programmed" cursor sizes in
               the example are grouped in the square brackets, but are also
               mutually exclusive.  Further, the "pre-programmed" sizes are
               exclusive from the programmable size specified in the
               [start,end] group.
