When using a macro to write information to a text file, you may want to add information to an existing file, rather than creating a new text file from scratch. To do this, all you need to do is open the file for Append rather than Output. The following code shows this process:
Open "MyFile.Dat" For Append As #1 For J = 1 to NewValues Print #1, UserVals(OrigVals + J) Next J Close #1
When the file is opened for Append mode, any new information is added to the end of the file, without disturbing the existing contents.
