Does anyone know about this switch? I just searched the DOS > help file on my Win98 CD, and no mention is made of it. Well, the mystery is solved. On usenet, someone reminded me that the switch is LFNFOR. You can type LFNFOR ON or LFNFOR OFF, or LFNFOR /? to get the help (Win9X). The help says that this switch 'Enables/Disables Long file names when processing For commands'. I post this for anyone else who might have had their interest piqued. Well, I searched the entire DOS help file on the Win98 Cd, and no mention of it was found. I know also, that there are some reserved DOS environmental variables, like DIRCMD, PATH, Prompt, Shell. Well, I guess the last 2 aren't really environment variables. I just wish there was a list of them, somewhere, because I think there are more. BTW, the full screen DOS help program that I use, is on the Win98 CD, in the Tools/oldmsdos folder. I just type 'Help' to get it. Well, I just noticed that it is only for version 6.22, so I don't know of a comprehensive help file for Win98 DOS, which, I guess is later than 6.22. 6.22 probably didn't have long file name support, so that explains why LFNFOR wasn't in the help file.
