I'm a former journalist on several computer magazine and know that a LOT of people rely on the informations that they get from them and other sources (like news and so on). The problem is that they don't have any way of verifying (is that a English word?) the information they receive! And when the informations are wrong they get confused! Like this one: PAHT DELETED (NAME DELETED) writes: >To get longer paths, you must increase your environment space. >To do this you have to place the following line into CONFIG.SYS: >SHELL=COMMAND.COM /P /E:2000 NO! >I think this should give you more than enough environment space. >If not, try it with /E:4000 instead of /E:2000. It sure does! >I hope this helps. It don't! It GIVES you are larger environment space but DOS won't allow a path that is longer than 128 bytes! Actually DOS don't allow any environment variable that's longer than ~128 bytes (including the name of the environment variable) How can I be so sure? Easy! I tried it out! I made this .BAT-file set TEST=%TEST%1234567890 And ran it several times until DOS rejected it (or actually the whole system went DOWN!!!!) and then counted the "1234567890"'s. There were 13, 13 * 10 = 130. That's so near 128 that you can get - near enough to make my point: TRY IT OUT BEFORE YOU SUBMIT YOUR WORDS OF WISDOM!!!!!!!!!!! <Shields up> <Power up system> <PANG> <Smoke> "What's up Doc" "We can't go to full power - only half" ~TO ALL ALIENS - PLEASE DO ONLY ATTACH US IF YOU MEAN IT - THANKS~ Leif Andrew Rump, AmbraSoft A/S, Roejelskaer 15, DK-2840 Holte (Denmark) UUCP: leif@ambra.dk, phone: +45 2424 111, touch phone: +45 422 817 + 313 > > > Why are tall Irish girls with red hair so wonderful ? ? ? < < <

I agree here. This only helps if the "Out of Environment Space" error appears when trying to set an environment variable. ... [some stuff deleted] >>I hope this helps. > >It don't!

[details of experiment using SET in a batch file deleted] What you are confusing here is what DOS can internally handle for an environment variable and the DOS command line buffer. The command line buffer is around 128 characters long. This is what limits the size of the environment variable when using the SET command. DOS itself can handle a PATH variable longer than 128 characters. The problem is how to get the value set in DOS's environment space. I have seen one or two utilties which directly mess around with DOS's internal environment space to create very long PATH variables. Unfortunately I do not remember the names of them{ > >TRY IT OUT BEFORE YOU SUBMIT YOUR WORDS OF WISDOM!!!!!!!!!!

I just confirmed this. I used "nset" from the PICNIX toolset to set
PATH=<approx. 160 characters of directories>;c:/bin, and was able to
execute a program from /bin.
