This may be true in "many DOS compilers," but NOT true in MS C 4.0. The
only limitation is that no *one* allocation may be more than 64k. You
have made a statement which at best is incorrect, and done a vast
disservice to anyone who wants to run C on DOS.

An outright laziness to post bullshit like this without ever reading the
manual or even checking with a tiny test program.

This entire posting is totally without valid technical comment. I have a
number of programs which allocate large address spaces, including
MicroEMACS and several proprietary editors. You should post a public
apology for this crap.

Disclamer: I was a beta tester for MSC 3 and 4, and we didn't miss
anything as blatent as missing large model. I don't have any financial
interest in MS, I'm just offended by a posting which starts from an
invalid technical point and then comments on the laziness of the
compiler writers and the immaturity of MSDOS software.
