IS.EXE HISTORY File Version 2.0 This is a complete re-write from scratch of the old IS utility. The dos version is compiled with Borland C++ 4.5 for DOS/WIN The os2 version is compiled with Borland C++ 2.0 for OS/2 I've never used, or seen the source for the original IS.EXE but I believe this should pretty much be identical in operation to the original.
