Who would have thought that the Bourne could still be introducing problems,
but I think we've just discovered one.
The following script-excerpt displays $1 (from the command line), then resets
all $n parameters (with --), it should assign the value "a" to $1, then
display the "a".
echo $1
set -- a
echo $1
When executed from the command line, it works. When executed from a program
with system() while not passing it any aruments, it works. Now give the same
script an argument, call it with system(),... and it fails. The second echo
still prints the command line argument, not the asigned "a".
We run Unix Sys V 3.1.1 on an AT&T 3B15. This is not so much a question
as it is a "watch out."
