11 05 Jan 08 SHL Move from arccnrs.c and comp.c to here
[920]12 06 Jan 08 GKY Add NormalizeCmdLine to check program strings on entry
[985]13 29 Feb 08 GKY Changes to enable user settable command line length
[1247]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.
