Worked OK for me so far, using this batch file
textcopy /Sw62242 /D "[cowden limited]" /Usa /P /Tpl /Cbody_word /W"WHERE plkey = 'B0001' " /Franges.doc /II
...where body_word is an image file.
But if a change the last I to an O to output the Word doc to a file, I get
"ERROR: Problem with file 'ranges.doc' ."
This happens whether or not the file already exists.
