/*
Note that the structure below defines the memory control
block (MCB) used by MS-DOS. This is an undocumented
structure. Through out Push.C and Pop.C the block[] array
is used instead of the MCB structure because, although the
structure is correct, Microsoft Quick C does not allow the
structure to be packed. As a result the MCB flag occupies
two bytes and thus makes the offsets of all of the other
variables incorrect.

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
