File Save As .
The Save As screen allows you to save a copy of the current job under
a new name. The copy that is created will then become the current
job.
The Save As dialog box is identical to that found in the
operating system. Simply enter a new name for the
current job and then tap the Save button.
Note: It is not necessary to include the .JOB extension
since it will automatically be added for you.
