- PathAssign V1.1
- ~~~~~~~~~~~~~~~
- Written by Anders `ALi' Lindgren
-
-
- Introduction
- ~~~~~~~~~~~~
- This is a program which increases the flexibility of the AmigaDOS
- system. The basic idea is to replace the old standard assignments
- with new which can read from a several different (i.e. a path) of
- directories. This operation is totaly transparent to the user and to
- normal programs.
-
- To use the program, read and follow the instructions found in the
- `Installation' paragraph below. Then read the `Function' and `Usage'
- section, or the supplied manual file `PathAss.man'
-
- If you are a novice, this text may seem a little `complicated', but
- don`t panic. The AmigaDOS and CLI is not so difficult, just try it
- and you will LOVE it. As a last resort, I can only recomend you to
- read one of the many books on the topic.
-
-
- Function:
- ~~~~~~~~~
- A PathAssignemnt works like a normal assignment, the difference lies
- in the fact that is can contain several directories. For example,
- the direcory HELLO: can be assignmed to `DF0:hi' AND `DF1:goodbye'.
- This is very helpful if there is useful files in several different
- disks and you would like to access them like they here stored in one
- single directory.
-
- The main reason to use this program is to gain more flexibility out
- of already existing programs. For examples the AmigaDOS make six
- different assignments at the startup. These are C:, S:, L:, LIBS:,
- DEVS: and FONTS:. These can be replaces by ekvivialent Path-
- Assignments so vd0:, df0: and df1: will be searched, for example.
-
- Everybody can benifit from this program, from one disk owners to
- people who has 300 Mb HDs, only your imagination will stop you!
- Here are some tips:
-
- - One drive (and two drive owners) with a shortage of RAM can
- place a few of their favorite commands on every disk. No
- irritating diskswapping will occoure.
-
- - Some comands and libraries can be placed in RAM: (or VD0:), the
- rest can be kept on a diskett.
-
- - HD owners sometimes don`t want to fill up their HD with several
- program (they do get filledup.) They simply can make a
- assignment to hd0:,RAD:,df0:,df1:,df2:,df3: and to every other
- device they own...
-
- - Lattice C and assembler programmers can place some often used
- headerfiles and libraries in RAM and place the rest on disk.
-
-
- The order of the directories are significant. The program scans the
- directories from the beginning so put the references to ram based
- devices first.
- NOTE: Files that don`t exist in any directory will be written to
- the first dir in the list!
-
- Note alse that PathAss doesn`t put put out any filerequesters, so if
- a file isn`t found, PathAss will return an error immediatley.
-
- Another feuture of this program is that it doesn`t consider
- assignments volume-relative, as the AmigaDos assignment command
- does. PathAss consider them device-relative. This means when an
- assignment is made to df0: PathAss will look at the volume currently
- is df0:, while Assign would check the volume that was inserted in
- df0: at the time of the assignment.
-
- To the advanced user:
- PathAssignments is implemented as normal AmigaDOS devices. The
- handler program is `Path-Handler'. This program handles almost
- every packet type existing on the Amiga. This code will search
- each specified directory in turn.
-
- To programmers: Don`t assume that the standard Amiga logical
- devices ARE assignments (i.e. DLT_DIRECTORY), they aren`t! (At
- least not on my system.)
-
-
- Usage:
- ~~~~~~
- To make a assigement write for examples:
- PathAss name: df1:,df0:
-
- If `name:' exists as a device or volume, the operation will fail,
- otherwise the system will have a new PathAssignment. If `name:' is
- a normal assignment or a PathAssignment it will be replaced with
- the new one. The PathAssignment will stay activated until it is
- deleted or replaced with an other PathAssignment.
-
- The dirs is separated with a comma. No blanks can be inserted
- between dirs. If a blank is embedded in a dirname, quote the whole
- string. Example:
- PathAss name: "hello:,hi there:"
-
- To list all current PathAssignments write:
- PathAss -l
-
- To delete an assignment write:
- PathAss -d name:
- or PathAss name:
-
- (Note: This also deletes old AmigaDos assignments)
-
- You can see a short help text by writing:
- PathAss -h
-
- If no arguments are specified, the PathAssignments will be listed if
- there exist any, otherwise the help text will be typed.
-
- Important: Because the komplexity (.Hmmm.) of AmigaDos and CLI, C:
- must be an assignment, I recommend the following workaround:
-
- Make a PathAssign to another device with the path that normally
- would have been the C: path. Then assign C: to that device.
-
- Example:
- PathAss CX: vd0:c,df0:c,df1:c
- Assign C: CX:
-
- I strongly suggest that you insert the PathAssignments in your
- startup-sequence file.
-
-
- Normal examples:
- PathAss devs: vd0:devs,df1:devs,df0:devs
- PathAss include: vd0:myinc,lattice5.0.2:CompactH
- PathAss fonts: vd0:fonts,df0:fonts,df1:fonts
- PathAss fonts:
- PathAss -l
- PathAss -h
- PathAss
- (Please note:)
- PathAss cx: vd0:c,df0:c,df1:c
- Assign c: cx:
-
-
- Insallation:
- ~~~~~~~~~~~~
-
- To use the program you put the file `path-handler' in your L:
- directory and the PathAss command in C:. For you non-CLI masters
- I have included the script `Install' to do this for you.
- (Type `Execute Install' at the CLI prompt.)
-
-
- Contents
- ~~~~~~~~
- The following files are included in the .zoo archive:
- PathAss - The actual command. Place it in C:
- Path-Handler - The device-handler. -----"----- L:
- PathAss.man - A manual file in UNIX-format.
- ReadMe.1.1 - This file
- Install - Script file to install PathAss.
- PathAll - Example Script file. PathAssigns
- all AmigaDos assignments to
- vd0:, df0: and df1:

- The PathAss program is shareware. To become a registred user just
- pay the fee, $10, to the address below. I will accept payment in
- any currency, like swedish crowns, new PD/SW programs, clean disks
- and so on. All registred users will recieve the lastest version of
- the program and the sourcecode. All registed users can send in an
- empty disk and return postage to get the absolute latest version of
- the program and source.
-
- To pay the fee, ask any question, complain, bug reports,
- suggestions, ask for autograps etc. Please write to:

- Credits:
- ~~~~~~~~
- I here give a big thanks for all of you who has sent is a ShareWare
- registrartion, it was beyond my wildest dreams that anyone would do
- that. I will also apologize for those who hasn`t heard of me while I
- was develloping V1.1. (I told my self next week, next week... But
- now it`s finally finished, I hope. You know, it takes a month to
- repair a broken computer here in Sweden :-( )
-
- A big thank goes to they who tested the prereleases, sent in
- bugreports, and to they who supported me morally by saying that they
- actually used my product, and liked it. (Hmmm, how about the SW
- notice.... :-) )
-
- Another big thanks goes to all other PD/SW devellopers around the
- world. Their effort has made the Amiga was it is today, i.e. a FUN
- machine to use.
-
-
- Background
- ~~~~~~~~~~
- The idea to this program first popped into my mind when I was
- thinking of an alternate method of storing the fonts in the Fonts:
- The reason why it become a complete program was because a friend of
- mine claimed that it couldn`t be done.
-
- The program was develloped om my Amiga 500 with 2 drives and a 2Mb
- memory expansion unit. It was developped using Lattice V 4.0, but
- the progran is now compiled with V 5.02.
-
-
- Future Fixes
- ~~~~~~~~~~~~
- In the occourance of free time, and user response, I have a few
- extra implementations to work on, these are among else:
-
- - Put out system requesters for volume relative access.
- (I maybe add a flag for this.)
-
- - Fix the memory bug in the release process of the resident
- segment. (Sorry, but this version is _late_ already).
-
- - Make the executable shorter, I might use the Arp librarys
- Printf() and Assign( ,NULL) functions. (So far I have written
- everything on my own.) I migth even rewrite some parts in
- Assembler.
-
- - Make the PathAss code pure. (Mabye it is, I don`t know.)
-
- - Multiple assignments and/or file (script) assignments.
-
- - Make the PathAssignments DLT_DIRECTORY`s, which in turn
- has locked a separate PATH:-device. This will fix the
- C: feature
-
- - Start the process only when accessed. This would save _some_
- memory. (At least 3Kb per device :-) )
