- FILE NAMES
- ==========
-
- Every type of file is uniquely identified in the OzGIS system. This means that
- the same name can be used for different types of files.
-
- e.g. the attribute and geographics example files for australia are both called
- "OZ".
-
- This is accomplished by the use of different extensions, so the two australian
- files are OZ.ATT and OZ.GEO
-
- However, you NEVER use the extensions to the file names; the system adds them
- automatically.
-
- The only time you have to worry about extensions is when handling files
- external to OzGIS e.g. backing up.
-
- One important point is that external data files have to have names with
- extensions ".DAT" before they can be read into the system (with OzEnter).
-
- A standard interface is used to give file names. You usually just type in the
- name (without extension) e.g. "PHRED". If the file is in another directory you
- can put that on the front e.g. "\MYDATA\PHRED". Similarly, files can be on
- other devices e.g. "A:PHRED" to read off a floppy.
-
- The \OZGIS directory is used to hold "system" files. These can be selected by
- typing "*" on the front of the file name. e.g. "*C16SV4" is the same as typing
- "\OZGIS\C16SV4". System files include device files, marker files and font files
- supplied with the system. You can of course put any files you use a lot into
- the OZGIS directory too.
-
-
- The file name interface has two other options. If you give the file name as "L"
- (or "l"), a list of all that type of file in the current directory and also any
- system files of that type, is generated.
-
- You can also give the file name as"E" (or "e"), which exits from the procedure
- back to the previous menu.
