Chapter 6: Understanding the File System

The .hp3070 File The system first searches the current working directory

for a .hp3070 file. If one is not found, the user’s home

directory is searched. This method allows a .hp3070

file for each board.

The .hp3070 file can affect system behavior in many

ways.

Some Descriptions of .hp3070 File Keywords

Some descriptions of .hp3070 file keywords are given

in Table 6-5. This is not a complete description of this

file. Other options are described beneath appropriate

topics throughout the 3070 User documentation.

.BackupLevel The value of this option sets the global backup style for this user and determines whether the system compilers keep an

unchanged copy (a backup) of files before modifying them, and how the backup is stored. The backup style can be:

none – No file backup is made.

numbered – Multiple backups are made as files change. To identify a numbered backup file, its name has a period, a

tilde (~), and a unique number from 1 to 9 appended to its name; for example, file.1~. Number 1 is the most recent

backup, and number 9 is the oldest. When more than 9 backups occur, the oldest backup file in the set is discarded and

those remaining are renumbered.

unnumbered – A single backup is made as files change. Each new backup file overwrites the contents of the previous

backup file. To identify an unnumbered backup file, a tilde (~) is appended to its name; for example, file~. For

example, .BackupLevel: unnumbered

Besides the global value for backup style, you can individually specify a backup style for some of the software modules in

your system. For example, Mpa.BackupLevel: numbered

overrides the global default and sets the backup style for the pin assignment software to numbered.
