Last change on this file since 1480 was 1480, checked in by Gregg Young, 16 years ago

Fix failure to correctly check for large file support in FindSwapperDat fall back code minor streamling. Add LVM.EXE to partition submenu. Stop using xDosQueryAppType where the file name it is passed is already a local stack variable. Correct a typo in several file header comments.

11 05 Jan 08 SHL Move from arccnrs.c and comp.c to here
12 06 Jan 08 GKY Add NormalizeCmdLine to check program strings on entry
13 29 Feb 08 GKY Changes to enable user settable command line length
14 15 Oct 08 GKY Fix NormalizeCmdLine to check all 5 executible extensions when no extension provided;
15 use searchapath to check for existance of file types not checked by DosQAppType;
16 close DosFind.
17 28 Jun 09 GKY Added AddBackslashToPath() to remove repeatative code
18 12 Jul 09 GKY Add xDosQueryAppType and xDosAlloc... to allow FM/2 to load in high memory
