You remember wrong. It's simply that if the reallocate call fails, DISPLAY won't load at all, and that is not desirable. >> Could it be made even smaller?

I can't just assume the disk/file will be there to reload. Anyway Eric, I won't discuss anymore about this. Be it public or private, it is boring to be talking about the same issues once and once again. If instead of talking you send me some code that works the way it is expected, I may merge it into the sources. >>>> Pretty stuck at using EDIT as a baseline replacement of MS EDIT. >>>> Other programs always welcome as extension. >>> >>> Well, the 64 kb file limit was a bit of a put-off for me, personally. >>> Maybe good for average use, I guess (just not my favorite preference). >> >> If only I could asume that there is ALWAYS a DPMI... ;))) > > There already are TDE, SETEDIT and others for 386 systems, > so I would keep EDIT free of that.

But it's a lot more complex ;) Aitor ------------------------------------------------------------------------------ All of the data generated in your IT infrastructure is seriously valuable. Why?
