The FORTRAN source files protel_min1_unix.for and protel_pad1_unix.for 
are set up to run on a non-SGI UNIX platform with a Fortran-77 compiler.
Delete the CONVERT=BIG_ENDIAN parameter from the OPEN(2... statements in
each file to use for SGI UNIX systems. The input data files are in SGI 
UNIX binary format.

The FORTRAN source files protel_min1_wpc.for and protel_pad1_wpc.for are
for modified versions of protel_min1_unix.for and protel_pad1_unix.for 
to run on a Microsoft Windows PC platform. Binary word byte reversal 
subroutines are specifically included in the wpc versions, while only the
CONVERT=BIG_ENDIAN parameter is needed for non-SGI UNIX. Note that the
record length parameter RECL in the OPEN statement for input data is 
given in bytes for Windows PC systems and in four-byte words for UNIX.

The *.lis files are sample outputs for orbit 15 from each source version.
