Stuart,
The problem
occurs at real TCL -- i.e. it's a UV problem, not an SB one
However, "NET
USER" is obviously smart enough to handle the problem with its
parameters
To
illustrate:
1) Create a
simple DOS batch file called "dsp.bat", in C:\tmp on your UV
server
It contains
only this:-
echo args(0) : %0
echo args(1) : %1
echo args(2)
: %2
echo args(3) : %3
echo args(4) :
%4 2) From a
real TCL prompt, do as you suggested:-
>DOS /c
"c:\tmp\dsp.bat -a:aaa -b:"bb bb" -c:ccc"
args (0) : c:\tmp\dsp.bat args (1) : -a:aaa args (2) : -b:" bb bb " args (3) : -c:ccc args (4) : Notice
that the second parameter is received by the DOS program as
"<space>bb<space>bb<space>", i.e. it has suddenly grown extra
leading and trailing spaces. !!! :-(
[Apparently NET
USER doesn't get too confused by this, but not all programs are so
robust]
Also notice
how intuitively obvious it is that the pair of double quotes inside the string
are being passed on to DOS rather than being interpreted as being matched with
the outside pair of double quotes as they would be every where else in
UV!!!
BTW, if you
change it to what would be more intuitive to a UV programmer, with single quotes
'outside' the double quotes ...
>DOS /c
'c:\tmp\dsp.bat -a:aaa -b:"bb bb" -c:ccc'
args (0) : c:\tmp\dsp.bat args (1) : -a:aaa args (2) : -b:\"bb bb\" args (3) : -c:ccc args (4) : The double
quotes get 'escaped' as <backslash><double
quote>
Or if you do
it the other way round, single quotes inside doubles, this
happens:-
>DOS /c
"c:\tmp\dsp.bat -a:aaa -b:'bb bb' -c:ccc"
args (0) : c:\tmp\dsp.bat args (1) : -a:aaa args (2) : -b:'bb args (3) : bb' args (4) : -c:ccc Sigh
Hope this
clarifies things
Mike
