Does anyone know how HIMEM.SYS (it comes with Microsoft C 6.0) works? The ram disk and codeview use it to access extended memory. I want to modify a program to do a swapping spawn on MS-DOS. That is, it should copy itself to extended memory, free nearly all of its memory, run the sub-process, and the bring itself back in. I could use the int 15h BIOS copy to do the copy in/ copy out, but if I can tie into HIMEM.SYS this could both simplify the problem and ensure compatibility with other extended memory uses. Anyone know how to tie into this driver or how I can find out? Thanks. -- Len Reed Holos Software, Inc. Voice: (404) 496-1358 UUCP: ...!gatech!holos0!lbr

MicroSoft will also send you a complete programmers technical book about HIMEM.SYS. A friend of mine called and they sent it to him free of charge. That was about two years ago. Ken kji@vpnet.chi.il.us
