C3023   Too many labels

     Explanation:  This error can occur if you are using automatic
     compilation to compile too many program files (.prg) into a single
     object file (.OBJ) at one time.

     Action:

     1. Try breaking the compile up into two or more smaller groups of files.

     2. Change your overall program building strategy to use single-file
        compilation where a single program file (.prg) is compiled into a
        single object file (.OBJ).  To compile using single-file compilation
        mode, use the /M option.
