       =============================================================

Source code:
~~~~~~~~~~~~
ugst-utl.c ... Float/short, Serial/Parallel conversion routines; scaling 
               routine.
ugst-utl.h ... Definitions for conversion and scaling routines.

Demo programs
~~~~~~~~~~~~~
spdemo.c ..... Demo for use of the serial/parallel conversion routines.
scaldemo.c ... Demo program with short/float conversion and scaling functions 
ugstdemo.h ... General UGST demo's include.

Makefiles:
~~~~~~~~~~
Makefiles have been provided for automatic build-up of the executable program
and to process the test files:
make-vms.com: ... DCL for VAX/VMS Vax-cc compiler or the VMS port of gcc
makefile.tcc: ... make file for MSDOS Borland tcc
makefile.djc: ... make file for MSDOS port of gcc
makefile.unx: ... make file for Unix, using either cc (Sun), acc (Sun), or gcc

Testing:
~~~~~~~~
The provided makefiles can run a portability test on the demo program. They 
need the archive tst-sp.zip ([pk]zip compatible archive) and [pk]unzip to 
extract the proper source and reference processed files. The contents of this
archive file is, as reported by unzip:

NOTE! These files are in the big-endian (high-byte first) format. Therefore, 
      before using under MSDOS or VAX/VMS, the files need to be byte-swapped.
