Not the current.
The EXTERNAL variable environ, i.e. the one that the kernel passed on,
which cannot be modified. You can only modify your local copy.
14:00 myname@tux64:~/tmp/c$ ls
a.c b.c
[trim]
14:00 myname@tux64:~/tmp/c$ ./a.out
a1: (null)
a2: MYVALUE
b: MYVALUE
14:00 myname@tux64:~/tmp/c$
your example shows a shell... i may have added to the confusion because a trick
i recall us doing in the DOS days was to change the master environment... after
running ./a.out, do you see your MYVAR in the environment via "set | more" or
"export | more" or whatever?? most likely you will not see your MYVAR at that
point after a.out finishes execution... i believe this is what was being pointed
to as not supported...
my apologies if i added confusion...
