Hi! This is for Clipper programmers. How do you access DOS variable from Clipper application? I am writing a network application that need to know the user name for certain operations. What I am trying to do is use DOS SET command to SET USER=SUNIL from NetWare login script and then read USER variable from Clipper to do some operations. I have Funcky and NetLib clipper libraries. Funcky does not have any functions to access DOS variables. NetLib has a Whoami function that can return the user's login name but I am trying to avoid extra overhead of linking NetLib library for just one function. Any suggestions or pointers to such utility are most welcome. Thanks in advance. sunil ~~~~~

From the Clipper Summer '87 manual, "Summary of Clipper Functions", page
6-8:
GETE(<expC>)
Returns the contents of a DOS environment variable specified by
<expC> as a character string.
So, you'd just do something like
USERNAME = GETE ("USER")
DO CASE
CASE USER = "SUNIL"

One way I have accessed the USER ID is to have the autoexec.bat file pass the station ID to the Clipper EXEcutable file. This is what your main.prg file would look like before compiling: Parameters user_id clear if type("user_id") = "U" user_id = "Un-Known" endif @ 10,10 say "Welcome " + user_id quit The autoexec.bat would look something like this: path c:\;c:\dos split ; set DOS error level to the station ID if errorlevel 1 goto serv1 if errorlevel 2 goto serv2 : : if errorlevel x goto servx :serv1 main TERM1 goto exit :serv2 main TERM2 goto exit . . . :exit Shawn R.

It seems to me that you should be able to use CLIPPER's own GETE() function to read DOS environment variables. See CLIPPER's reference manual, Page 6-96. However, I have never tried this in a network environment. Hope this helps. Sajjad Ahrabi
