All you need to do is set the file's Read-Only attribute bit.
The easiest way to do this is to use one of the many available
programs that let you monkey with file attributes -- CHMODE (aka CHMOD)
is probably the most popular; TCHMOD is another I know of, as well as
one of the programs that comes with the Norton Utilities (I forget
its name, I think it's FA.COM or something like that).  With CHMODE,
you just say
		chmode +r filename

Kind of like the way you'd do it with Unix.

If you want to do it programmatically, there's a dos function called
Get/Set Attribute.  Unfortunately, I don't have its specifics in front
of me so I'll leave it to someone else to describe it to you, or you
can look it up in any handy-dandy MS-DOS Programmer's Reference Manual ...
