8086 pointers

[D Murphy]

Never having had occasion to require this before, I wonder if I declared:

char *foo;

and wanted to use foo to hold a string which would be passed to a DOS
function which worked on a string starting at an address in DS:DX, is
'foo' equal to the offset of that address, or the full 20 bit address ?
More to the point, if it is equal to the 20 bit address, how do I find
what the segment address, DS, is so I can find the offset ?

Please reply directly to me, as I don't read this group much. I'll summarize
any replies.

Thanx,
Murff......
