-
- NAME
- Assign - Binds a device name to a directory or file.
-
- SYNOPSIS
- 1.3
- Assign Name Dir Etc/... LIST EXISTS REMOVE
-
- 2.x/3.x
- Assign Name Dir Etc/... LIST EXISTS DISMOUNT
- DEFER PATH ADD REMOVE VOLS DIRS DEVICES
-
- DESCRIPTION
- Assign causes NAME: to be a synonym for a directory
- or a pathname. This is referred to as a "logical"
- device, since it appears to the Amiga and the user as a
- device, but is in fact a directory. You can use this as a
- convenient shorthand to refer to lengthy pathnames, or to
- refer to a variety of different directories by the same
- name (just change the assignment when you want the
- program to change directories).
-
- You can remove assignments by giving only NAME:, or
- by giving a single minus ('-') as the directory or device
- name. There are also specifice keywords to remove
- assigns which will be covered later. In any case, all
- assigns are lost when the system is shut off or rebooted.
-
- In 2.x/3.x you can assign a single device name to
- many directories by simply listing all of the directories
- after the device name.
-
- S:, L:, C:, FONTS:, DEVS:, LIBS:, T:, and SYS: are
- all made during normal startups. All these assigns
- directly relate with system operation. Therefor, they
- should not be tampered with unless you are prepared to
- crash your system! So, don't mess with system assigns
- unless you know absolutly what you are doing...
-
- If there is already a directory with an assignment,
- any new assignment will replace it. You cannot, however,
- assign the same name to a device that already exists. So
- an assign to device Work: if a disk whose name Work: is
- already mounted.
-
-
-
- OPTIONS
- LIST
- Lists the current assignments. Under 1.3, if you
- specify a single already assigned name on the command
- line with LIST, it will be removed from the device list.
- Under 2.x/ 3.x you can either make or remove assignments
- along with listing them.
-
- EXISTS
- Takes a logical device name as an argument. If the
- name exists, the device name and its assignment are
- displayed. If the name does not exist, then the
- condition flag is set to WARN (return flag 5). This will
- cause an IF WARN batch file statement to succeed.
-
- REMOVE
- For 1.3: Takes a logical device name as an argument,
- and removes it from the device list. This is useful
- largely to individuals writing handlers, careless use of
- this option can easily crash the Amiga. It will not,
- however free up the memory that was taken up with the
- assign.
-
- For 2.x/3.x: It can be used to delete one directory
- from a list of assigns. Opposite of ADD (see below).
-
- DISMOUNT
- 2.X/3.X ONLY: Used exactly like the REMOVE keyword
- for 1.3 to remove a device from a list of mounted
- devices.
-
- DEFER
- 2.x/3.x Only: Postpones the assign until a command
- tries to access that device. Defer will not throw out an
- error if it searches for a directory and it does not
- exist.
-
-
- PATH
- 2.x/3.x Only: This expands on the DEFER keyword.
- Whereas DEFER eventually binds the assign, PATH keeps the
- assign non-binding. Not only will it wait for a command
- to access that device, but it will reevaluate the assign
- every other time that device is requested for. (NB: This
- is very convenient if you are a floppy only user. You
- will not have to replace the Workbench each time FONTS:
- is requested. Instead, you can insert different floppy
- named fonts: each time that device is scanned for.)
-
- PATH will not accept multi directory assigns.
-
- ADD
- 2.x/3.x Only: Let's you add new directories to an
- existing assign. For instance, if you assign a device
- that is alread assigned you will lose your old assign. If
- you use the ADD keyword, you will add the new assign to
- the old assign.
-
- VOLS
- DIRS
- DEVICES
- 2.x/3.x Only: Limits the information that is
- displayed when you list your assigns. VOLS shows you only
- which volumes are assigned, DIRS shows you only which
- directories are assigned. DEVICES shows you only which
- devices are assigned. If none of these keywords are used
- then all three kind of information are displayed.
-
- CAUTIONS
- Random or careless assignments of the Amiga's
- pre-assigned devices can cause mass confusion.
-
- Random or careless use of the REMOVE option can cause
- a GURU (and crash your sytem).

- EXAMPLES
-
- 1.
- ASSIGN DICTIONARY: df1:usr/lib/dictionary
-
- DICTIONARY: may now be used as a synonym for the
- complete path df1:usr/lib/dictionary. If a program uses
- the logical device DICTIONARY: rather than a hardcoded
- directory name, then changing the DICTIONARY: assignment
- will change the dictionary that the program will use.
-
- Assign allows a practically infinite number of
- assignments or deletions to be made on one command line.
- You may remove an assignment by using a minus '-' sign
- instead of a logical directory or filename to subtract
- this assignment from the device list.
-
- 2. To return all the assignments made to your system
- just enter:
-
- Assign
-
- 3. 1.3 Only:
-
- To assign POOF: to the disk in DF0:, remove the
- assignments for PUF: and DUF: and assigns CRUFT: to HD0:.
-
- ASSIGN POOF: DF0: PUF: - DUF: - CRUFT: HD0:
-
-
- 4.2.x/3.x Only:
-
- To assign multiple paths to one device:
-
- Assign Music: Work:DeliTracker/Mods Work:OctaMed/Meds
-
-
- To assign Fonts: to df0:Fonts only when a program tries to
- access Fonts:
-
- Assign Fonts: Df0:Fonts DEFER
