WRITE { ON LFN | OFf | Reuse | Unique }

Echo all commands to the journal file LFN or not. The default name for the journal file is ttyinp or a unique name formed by changing the last letter.

WRITE ON enables writing to the journal file;

WRITE OFF disables it.

REUSE and UNIQUE control the proliferation of journal files. The journal file ttyinp is REUSEd on each Sabrina execution or a new file is created with a UNIQUE name. The unique file names are formed by starting with ttyin and incrementing the last letter, resulting in files ttyinq, ttyinr, ttyins... ttyinz, ttyina....
