I don't know whether your post is related to my earlier message or
it is just that we both have had the same problem.<br>
<br>
Unfortunately the documentation isn't clear enough, for instance
it says:<br>
<br>
commands <br>
Single text containing instructions sent to the MS Windows
cmd.exe command interpreter.<br>
<br>
but it doesn't say how the instructions should be connected. They
could be separated by commas, by spaces, by semicolons...
Seemingly it is by spaces (at least this way the bOK argumet is
True), but there could be some ambiguity, for instance if one
wants to change directory and the directory contains two words and
the second is also a command or a program.<br>
<br>
On the other hand the expression "single text" is not clear. What
is a "text" in Scilab? Text is meaningless, in Scilab we have
strings, and "single" is somewhat vague. Does it mean a
one-component string?<br>
<br>
Your workaround of using a batch may work, but it requires the
extra job of creating and saving it and at the end deleting it,
which should be automatic.<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

<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>
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>
