I do the following:<br>
<br>
comands = "start | dir H:\ "<br>
dos(comands, "-echo")<br>
<br>
Then a command line DOS window opens at the workihg directory of
Scilab, and doesn't close.<br>
<br>
Any further action I attempt with Scilab causes a program crash. The
same happens without the pipe symbol |.<br>

<br>
This has been queried previously without an obvious solution.<br>
<br>
For example: [output, bOK]=dos('grdinfo Test_10-FAA.grd')<br>
Fails with bOK = F<br>
<br>
Adding 'start grdinfo Test_10-FAA.grd gives bOK=T but now dos
window console with the result<br>
<br>
The only way to get the out put shown below is to put the
commands into a bathch file:<br>
grd-info.bat (containing the command stream grdinfo
Test_10-FAA.grd<br>
<br>
Such that the dos function becomes: [out,TF]=dos('start
grd-info.bat'); out, TF<br>
<br>
\D_Drive\Geoscience\Scilab>grdinfo Test_10-FAA.grd<br>

<br>
However, even with this workaround, nothing is written to the
variable 'out'. The program 'grdinfo' is in the Windows path, so
should be run without using start. In the past, the function did
work. Basic Windows commands like {out, TF]=dos('dir') works.<br>
<br>
I have verified that nothing is written to the consolebox. In
addition, this is a new computer and new install of Scilab 6.1.1<br>
Also, the same function under Octave runs correctly as
dos('grdinfo Test_10-FAA.grd'), and I am assuming the Scilab
version should behave the same.<br>
<br>
Since the mailinglists section is no longer functional, I cannot
check for possible solutions or pointers. Apologies if this is
repeating my previous query on the issue.<br>
<br>
Thanks<br>
