Viewing Catalogs and Saving Files

Saving a File

You need to use a filename that does not already exist in the current directory. The filename is limited to eight characters, alpha (A-Z) or numeric (0-9) in any combination. The analyzer will not allow you to overwrite an existing file. If you select a filename that already exists, the status bar will display the message: File already exists. If you do not choose a filename, the analyzer will automatically generate a name based on the type of file you are saving (Setup: SETUP, State: STATE, Trace: TRACE, Limits: LIMIT, Corrections: COREC, Screen: SCREN). It also generates a three digit integer (starting at 000 and extending through 999, remembering the previously saved value through a power cycle) which it adds to the name, for example: TRACE056.TRC. Also note that this three digit integer increments upon each attempted save until a unique filename is created, without regard to the success of the save.

6.The destination for the saved file is shown in the Path: field. In this example, you will select the path as C:\START\. If the correct location is not listed in the Path: field, change directories as follows:

a.Press Dir Up or Dir Select and use the step keys or knob, to highlight the desired destination directory.

b.Press Dir Select and confirm your choice displayed in the Path: field.

7.Press Save Now or Save (hardkey) to save the file to the C:\Start\ location. The message Saving Now is displayed during this operation. For this example, the status line displays:

C:\START\TEST1.TRC file saved.

When saving to drive (A:), never remove the floppy disk during the save operation. To do so could corrupt all data on the floppy disk.
