- CloseWorkBench v1.0

-
- This is a set of two utilities which open and close the Workbench
- screen on demand. They are designed to be used in combination
- with other utilities, such as AutoPubScreen, that open their own
- screens and you wish to save memory by closing the Workbench
- screen. It also acts as a screen blanker and keyboard lock if
- the Workbench is the only screen open. :-)
-
- Please send any flames, bug reports, etc to the author.

-
- Background:
-
-
- I originally wrote this program in C so that I could run Term
- (by Olaf Barthel - best 'comm program ever) on its own screen
- on an Amiga 500 with only 1mb of memory. Term didn't leave a lot
- of memory left on that machine, so every little bit helped.
- Then I bought an Amiga 1200, and had a different problem. I
- wanted an 8 colour Workbench screen, but only 4 colours for CLI
- windows. I had a Multiscan monitor for a while, and it was also
- nice to have Workbench on a DBLNTSC screen, with CLI on a non-
- interlaced screen so I could read it better. I started using
- PSX (Steve Tibbett) to open a public screen, and opened all
- my CLI windows here. I insert my "CloseWorkBench" command into
- the S:Shell-Startup file, and every time I hotkey a new CLI
- (using KCommodity, QMouse, or whatever), the Workbench would
- close down and I'd get my CLI on a (faster) screen with less
- colours. I re-wrote in Assembler in order to return result
- codes and to reduce the size. Its now about 20% of the original
- size.
-
- The one problem with this is that I always had that screen open.
- This problem is solved by using AutoPubScreen. (Steve Lemieux -
- it can be found on Aminet and is highly recommended with this
- program) This program opens up a new public screen whenever it
- is needed. So if you start a shell with the line
-
- NEWSHELL "CON:0/0/640/400/MyShell/Screen MyScreen"
-
- the screen "MyScreen" will be opened if necessary. Additionally,
- this screen will be closed automatically once all windows on the
- screen are closed. Perfect! 8 colour WorkBench, 4 colour CLI,
- each only opened as required.
-
-
- Installation:
-
-
- Simply copy the two files to somewhere where your path can find
- them, such as C:
-
-
- Usage:
-
- CloseWorkBench - 308 bytes (91 byte version string)
-
- - takes no parameters or tooltypes.
- - runs from an icon. This has an neat effect if you have
- an "exploding windows" program like KCommodity running!
- - returns the following result codes:
- 0 - Workbench closed.
- 5 - Workbench not closed, either because it wasn't
- open or there is a "visitor" window on the
- Workbench screen. Not really too serious.
- 20 - Intuition.library could not be opened. You
- should consider this a serious error. If you
- see this you're probably headed for a GURU
- because you've got to be in bad shape to get
- this error.
- - don't close the Workbench screen if you don't have
- anything else running! (Don't say I didn't warn you!)
- - once all other screens are closed, Workbench will auto-
- matically re-open. But only if a screen was open before
- CloseWorkBench was started.
-
- OpenWorkBench - 204 bytes (91 byte version string)
-
- - takes no parameters
- - does not run from an icon. This would be pretty
- pointless anyway.
- - returns the following result codes:
- 0 - Workbench opened.
- 10 - Workbench not opened. Either Workbench is not
- running, or their is something wrong with
- Intuition. Consider this a fairly serious
- error. Either user screwed up, or Intuition did.
- 20 - Intuition.library could not be opened. See
- above for general comments.
-
-
- Bugs:
-
-
- Closing the Workbench screen when it is the only screen opened may
- result in an unusable system. If you can hotkey some other
- program active, you will be OK. If not, you must give the Amiga a
- three finger salute. (Ctrl-Amiga-Amiga) This is _NOT_ a bug. It
- is a "KeyBoard / Screen Blanker / Lock" Under DOS 1.3 it also
- becomes a mouse excerciser; under DOS 2.04 and 3.0 it becomes a
- mouse blanker. I suppose this could be fixed by checking to see
- whether other screens are open...
-
- As the RKM's say, "The name of this function is improperly
- spelled. Should be (Open)CloseWorkbench."* I wouldn't worry
- about this too much if your using AmigaDOS; it takes your input
- either way. :-) Tested on an Amiga 500 (512K chip, 512 fast,
- ECS, DOS 2.04 & 1.3) and Amiga 1200 (2mb chip, AGA, DOS 3.0)
