Re: Deleting Files

["ig" fbarrau@xxxxxxxx]

 If you are (as Carl said) using Xy3 and cant use a U2 subrutin to erase
the files and then go back to xy to continue your program without answering
the y/n question, you can use Carls DOS command, but with an
ECHO command and a pipe <|> to send the "y" that the del program is asking
for:

Xy3:
 DOS /C ECHO Y | DEL *.*

Xy4:
 DOS/NV/Z /C ECHO Y | DEL *.*

  Of course, be carefull with it, perhaps you can fill the full path to
avoid fatal erases:

BC DOS /C ECHO Y | DEL C:\HERE\THERE\*.*

(I supose you are in a english windows or dos version, in spanish I use S/N
instead of Y/N)
