I am trying to call an external programme form a Scheme file. Here is the
command-prompt script that does what I would like to do: 
"C:\Program Files\IrfanView\i_view32.exe" c:\ec-ref\referents\*.jpg
/resample=(0,100) /aspectratio /convert=c:\ec-ref\ref-thumbs\*.jpg
In Scheme, I tried with "process" and "shell-execute" but I could only
succede to open a file with the external programme. I am unable to pass the
parameters (  /resample=(0,100) /aspectratio
/convert=c:\ec-ref\ref-thumbs\*.jpg /killmesoftly   )   
I would be grateful for any suggestions!
Thank you!
