I. Introduction
        RCG is a FORTRAN77 program initially coded (1964-65) on the 
IBM 7030 ("Stretch"), and subsequently modified (with addition of 
many new features and options) to run on other IBM, CDC, and CRAY 
mainframes, various VAXs and MicroVAXs, SUN and IBM RISC 
workstations, and finally Power Macintosh computers using the 
Language Systems or Absoft FORTRAN compilers and PCs using the free
GNU g77 compiler.  It has also been successfully used on Apollo, 
Hewlett-Packard, and SGI computers.  On 32-bit-word machines, it 
should be run in double-precision mode--preferably using, if 
available, a large-exponent-range option (10
