I'm working on porting a Turbo Pascal Unit to LightSpeed Pascal, and I've
hit a catch.  In the Turbo Unit, the high bit of an integer is set with

	foo := $8000 ;	{set high bit -- value is -32768}

But, LightSpeed won't accept that -- it complains that the
"constant (whose value is -32768) is out of range".

I thought that the range of ints was supposed to be -32768 to +32767.
I've tried the obvious "hacks", with no luck.  For instance:

	i := -32767 ;
	i := i-1 ;	{nope -- int overflow}
or
	i := -16384 ;
	i := 2 * i ;	{ditto}

I don't know why (yet) but the Unit does not work properly if "foo" does not
have the high bit set.

I'm using LSP 1.0.  Can anyone please help me?  Will a more recent version
of LSP help? 

Karl
