Oracle Forms

Hi,
Im using Webutil in a form. Client_Text_IO is first used to generate a file thro fopen.
lc_file := c:\abc.txt

However when i try to copy the same file into a destination it doesn't work.Im using

Client_Host('copy'||lc_file||'lpt1',NO_SCREEN);

The java console gives the the following msg.

Setting property WUH_EXECUTION_MODE to 0
Setting property WUH_EXECUTE to copy c:\abc.txt
Getting property WUH_EXECUTE
Setting property WUH_PROC_ID to 2
Getting property WUH_RC
Setting property WUH_CLEAR_PROC to 2

Pl. suggest how to make the copy command work ?Where am I going wrong?

Regds,
Shruti.
