How do I edit a record on a CD-ROM, a web site, or an FTP server?

Be sure that your current directory is writable, that both your current directory and the source (CD-ROM, web, or FTP) directory containing the record you wish to edit are in your WFDB path, and that your current directory comes before the source directory in your WFDB path. When WAVE writes your edits, they always go into the current directory (so the current directory cannot be on the CD-ROM, since the CD-ROM is not writable). At a later time, when WAVE (or any other WFDB application) opens the record, it finds your edited version first, and doesn't look for the original version, provided only that, in your WFDB path, the source directory follows the one in which your edits are stored.
