- XICON
- *********
-
- With this program you can execute a file of AmigaDOS CLI commands
- directly from a WorkBench window, rather than from the CLI, simply by
- double-clicking an associated icon in the window. A full-screen window
- will be opened to display the output of the commands. To close the
- window again type a control-C (or control-D) -- or it can be configured to
- close automatically by setting the ToolType 'MODE=closewindow' in the
- icon.
-
- You also have the option of executing commands from the ToolTypes lines
- of the icon itself, if you specify them with the 'CMD=...' ToolType.
- (There are advantages and disadvantages to this.)
-
- The icon you click on must always have a file associated with it in order
- to keep WorkBench happy, but this needn't NECESSARILY be a list of CLI
- commands; if you set 'MODE=noscript' it can be any type of data; you can
- operate on it if you want with commands in the ToolTypes list.
-
- You can select more than one icon at a time if you like, by holding down
- the Shift key as you click on each. Only DOUBLE-click on the LAST selection
- (or use the "Open" item in the WorkBench Menu -- see "Introduction to
- Amiga").
-
-
-
- Setup: You can install Xicon itself in any convenient directory: the
- best is probably either the 'C:' directory of your Workbench disk
- or its root directory ('SYS:'). (It doesn't need an icon of its own.)
- Whichever directory you use, the icons that are going to invoke it must
- have a matching pathname as their DEFAULT TOOL (see below).
-
- You can put an icon and its associated file in any directory ("drawer")
- that you can open under WorkBench. The file must of course have the same
- name as the icon (without the '.info' extension the icon has tacked on).
- Each icon must be of type 'PROJECT' with a DEFAULT TOOL string specifying
- a path to the Xicon program. If it is in the same directory, 'xicon' will
- suffice, otherwise you must use the complete pathname.
-
-
-
- Command Scripts: There are many ways to generate Command Script files
- with their icons. One simple approach is to duplicate
- the "democommand" supplied and rename it (using WorkBench Menu operations),
- then go to the CLI and modify the text file using whatever editor you are
- comfortable with. If xicon is not in the local directory, you will also
- have to change the Default Tool in the icon to the correct pathname.
-
- Alternatively you can create the text file first (let's call it 'myscript'),
- then use the CLI to copy a suitable project icon ('democommand.info' for
- instance) to 'myscript.info' and modify it as necessary.
-
-
-
- Modifying an icon: All the changes you should need to make to an icon
- can be done with the 'Info' item in the WorkBench
- Menu. Select the icon you want to modify by clicking on it, depress the
- right mouse button to bring up the menu, and select 'Info' from the
- 'WorkBench' section. This should bring up an information window for
- that icon.
-
- To set the DEFAULT TOOL, click in that gadget and type in (or edit) the
- string.
-
- To enter a new TOOL TYPE, click first on the ADD gadget, then click in the
- string gadget and type it in. If you want to insert it into an existing
- set, use the arrow gadgets on the left to move to the desired point first.
- You can of course edit the strings in the usual way. Use the DEL gadget
- to remove a line completely.
-
- When you are done, click in the SAVE box to preserve the changes.
-
-
-
- MODE Setting: You can alter the assumptions made by Xicon by setting the
- Tool Type 'MODE'.
-
- 'MODE=closewindow' avoids having to type control-C to terminate
- the program. The window will close as soon as all the commands
- have completed.
-
- 'MODE=noscript' prevents Xicon from trying to read commands from
- its associated file, so this can be of any type. This option only
- makes sense if the 'CMD=' Tool Type is used to supply the commands.
-
- Only one MODE entry will be recognized in the Tool Types array, so if you
- want both the above options, specify 'MODE=noscript|closewindow'.
-
-
- Commands in the Icon: Instead of a script file, you can specify commands
- directly in the Tool Types array of the icon, with
- the 'CMD=command string' format. (For example: 'CMD=list df1:work'.)
-
- Include as many of these as you like. They will be executed in sequence,
- but each by a separate CLI process, so you can't use a command to set
- parameters like stack size or current directory for the ones that follow.
- A Command Script file on the other hand is executed completely by one
- process, so settings are inherited.
-
-
-
- Caveats:
-
- There is no provision at the moment for changing the size of the display
- window -- it is always full-screen. A later version may allow you to
- specify this via the TOOLTYPES strings in the icon.
-
- The most annoying defect is that the "Execute()" system call used by
- xicon loses track of the current directory when invoked by a WorkBench
- program (it switches to DF0:). I've tried a lot of tricks to correct
- this, without success, so -- if you want to list the directory or
- something -- I'm afraid you always have to specify a FULL pathname
- somewhere in the command script. Sorry. If you have several commands
- in your script, make a suitable 'CD mydisk:mydir' your first command.
-
- The "Execute" referred to above is NOT the DOS "EXECUTE" Command, by the
- way, in case anyone is confused. Actually it requires the DOS "RUN"
- command -- which must be available in the "C:" directory -- for its
- operation. (Now I'll bet you're confused again...)
-
- Because xicon's method of calling Execute() sets up the command
- file as the input stream, the output window cannot be used as a
- console. So if a command needs keyboard input it must open up its own
- console window using I/O redirection, e.g.:
-
- mycommand <CON:0/100/150/50/input
-
- (It would likely be a program of your own, because DOS commands don't
- usually ask for input, unless you use the "?" option in the command
- line. Although, for an example, see the "Set Date" command file in this
- directory.) You might also want to try "EXECUTE CON:0/100/150/50/exec"
- --or whatever you have renamed that command as. (To get out of the
- mini-CLI you just created, use 'control-\'.)
-
- The initial stack size is always 4000 bytes. You can change this in
- your command script with a sutitable STACK command. Note that the
- STACK gadget in the icon Info window does not have any effect. (Except
- on the stack used by Xicon itself! I haven't investigated how much
- it needs.)
-
- You cannot interrupt a command sequence with control-C or control-D
- (because the input stream has been diverted), although output can be
- paused with the space bar in the usual way. Be careful not to write
- a command file that can get "stuck", or you will never be able to
- close that window.
-
- Unfortunately DOS won't let you use IF, SKIP, QUIT, and so on in
- these command files, and of course argument expansion is not available.
-
- I really SHOULD have supplied some kind of close gadget for the window,
- rather than requiring the user to type control-C, but locating a
- window opened as a DOS Console is a pain, so maybe another time...

- TICON
- *********
-
- This program allows the user to display a text file by double-clicking
- on an associated icon. You are probably reading this file under its
- management. The pause at the end of each screenful is automatic.
-
-
- Setup: Essentially identical to the procedures for Xicon above, except
- that the file is displayed rather than executed, and the
- DEFAULT TOOL is "TICON". Any simple text file may be used, provided it is
- sensibly formatted (with newlines in the right places).
-
-
- Restrictions: This is just a crude and simple text reading program. You
- can't backtrack or skip forward. You can, however, abort
- at any point with control-C. (If it is waiting for a return, you will have
- to type this after the control-C. The window won't close until you type a
- second control-C.)
-
- There are no Tool Type options.

- Coda
-
- I hope you find these programs useful. If you do, please pass them around
- freely. I suggest you copy the entire drawer -- with its demo and source
- files -- by dragging its icon to another disk. (You won't see either the
- programs or their sources in the WorkBench window; they don't have icons.
- You can only get at them using the CLI.)
-
- I'll welcome any feedback you wish to give. My address is at the top.
- Watch for some Shareware following not too far behind in this same pipe...
- Over the last few months I have been developing an enhanced CLI system.
- Unlike Xicon -- and all the other similar developments that I know of --
- it does NOT use the Execute() call; instead, it handles all its own
- facilities and provides total upward compatibility with the standard CLI.
- Even at its present stage it is installed as my standard user interface.
- (I'll leave you in suspense as to the extra features it will have for now.
- When it is released you can check them out for yourself...)
