The program CONVERT is an all-purpose Metric - English 
conversion utility.  This file contains some general 
information on its use.

The program is written in Borland Turbo-C.  It is slightly
smaller than 40-K bytes in size and should require only 
128-K bytes of RAM.  

Normally, the program writes its display information directly
to the video memory of the PC.  This of course provides the
fastest display performance possible at the expense of broad
compatability with those PC's which are not fully compatible
with the IBM PC.  For this reason, the program is capable of 
using BIOS calls to write to the screen instead.

The program does this by checking the DOS environment for a
variable named UPDATEMODE.  If it finds this variable set to
BIOS, it uses the bios mode.  If it is set to DIRECT, or not 
set at all, the direct mode is used.  If UPDATEMODE is set 
equal to anything other than bios or direct, an error message
is shown and program execution terminates.

To make the program use the BIOS mode, the user need only 
type "set updatemode=bios" at the DOS prompt, or add this
line to the AUTOEXEC.BAT file.

There are thirty six conversions available.  To select a
specific conversion automatically, enter its number on the
command line when starting the program.  For example, enter
"CONVERT 27" to put you directly into the cubic centimetres
to cubic inches conversion.
