The only way I can explain this, is having different PATH values
between the two shells. This may include the current directory if "."
is in the PATH (dunno if it's possible in Windows).

Try cd-ing to the same directory in both cmd.exe and tclsh.exe before
trying this.

The current directory is *always* searched for things to execute on
Windows. IIRC, it's searched before looking at the PATH.

Ok. I've found the cause of error message of "exec" command. It seems
to me that contrary of my undestanding of the doc, on WinXP the exec
command *doesn't* search the file to be executed in the PATH
environnement variable :
() 1 % pwd
C:/
() 2 % puts $env(PATH)
C:\Program Files\ImageMagick-6.6.3-Q16;C:\Program Files\Seagate

Systems Corp\Gemalto\Access Client\v5\
() 3 % file exists logo.bmp
1
() 4 % exec convert logo.bmp logo.gif
ParamÅ tre non valide - logo.gif
() 5 %

The file convert.exe *is* in C:\Program Files\ImageMagick-6.6.3-Q16
directory.

Observation : IMHO, the error message produced by exec not finding the
file to execute is clearly wrong...

It looks like the message is comming from your convert program NOT
from exec. It has nothing to do with the PATH, you could try
explicitly exec'ing convert.exe as any stray convert.com/convert.bat
could cause trouble.

Hi Martyn,

I'm not sure if Tcl can forward error message from a subprocess being
executed at the OS level. If it does, that's nice.

But, in my preceding post, convert.exe was not executed at all.

I've just uninstalled my old ImageMagick suite.
Prior to re-install a newer relase of ImageMagick, here is what I
did :

() 1 % pwd
C:/
() 2 % file exists logo.bmp
1
() 3 % exec convert logo.bmp logo.gif
ParamÅ tre non valide - logo.gif
() 4 %

Here the file convert.exe doesn't exist any more on my HD...
