The fax routine that I wrote was faxing existing tif files.

You might want to do

REPORT FORM PO TO FILE MyFile ASCII

Save the report on a temp folder and then use the

oNewMessage.Files.Add("C:\temp\MyFile.TXT")

>>The question I have is how to replace the attachment variable (paFichEnviar) with the following code at runtime:

paFichEnvia = c:\temp\MyFile.txt
