Basic procedures:
-----------------------
gener  - Input parameter is the name of input file *.ufo (without
         extension), which is copied into file P.UFO. If no input
         parameter is used, file p.standard is copied into P.UFO.
         File P.UFO is an input file of the UFO preprocessor BEL.
         The Fortran control program P.F is an output file of the  
         compil procedure.
compil - Input parameter is the name of output file *.OUT (without
         extension), which is used as a basic text output of the UFO
         system. If no input parameter is given, file P.OUT is used.
         Control program P.F, created by the UFO preprocessor, is 
         compiled by the fortran compiler and the resulting file 
         p is executed. File *.OUT is used as a basic text output 
         of the UFO system.
ufogo  - Input parameter is the name of input and output files 
         *.ufo and *.OUT (without extension), which is copied into 
         file P.UFO. If no input parameter is used, file p.standard 
         is copied into P.UFO. File P.UFO is an input file of the 
         UFO preprocessor BEL. control program P.F, created by the 
         UFO preprocessor, is compiled by the fortran compiler and 
         the resulting file p is executed. File *.OUT is used as 
         a basic text output of the UFO system.
