Please Help

[Resperger]

I start using gnu 7.06 or 7.05 and I have an issue with an error message
which I do not understand.
 
I use a command like 
 
gswin32c.exe -@ string.txt
 
string.txt look like this:
 
-Ic:\gs\gs7.05\bin;c:\gs\fonts -dNOPAUSE -dBATCH -sDEVICE=pdfwrite
-sPAPERSIZE=a4 -sOUTPUTFILE=c:\temp\file.pdf c:\temp\wb652879.ps
 
I get the error:
/undefined in -Ic:\gem\gs7.05\bin;c:\gs\fonts
 
and I cannot find out what is wrong.
 
TIA
