Lester,
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.
Unfortunately the documentation isn't clear enough, for instance it says:
commands
Single text containing instructions sent to the MS Windows cmd.exe
command interpreter.
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.
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?
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.
Regards,
Federico Miyara

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

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.
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
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.
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.
Thanks
Lester
