- PSX 1.1 (PublicScreenX)
-
- A 2.0 Public Screen Manager
-
- by Steve Tibbett
-
-
- ---
- UPDATE NOTE: PSX 1.1 is PSX 1.0 with some enforcer hits removed, and
- with the addition of a DISPLAYID keyword when starting from CLI. If
- you've got the CBM includes then you can specify a DisplayID as a hex
- number as in PSX OPEN Phred DISPLAYID 0x8000 (to get a hires screen).
-
- Also, 1.1 changes the way the MAKEDEFAULT keyword works. MAKEDEFAULT
- is now /K instead of /S, meaning it now needs a string. So to open
- Phred and have it be the default, you'd need to do something like
- PSX OPEN PHRED MAKEDEFAULT PHRED.
- ---
-
- PSX is a utility that won't mean much to you unless you have programs that
- use public screens, or you need to have a public screen around to open
- windows on.
-
- PSX can be run with no arguments, in which case it will open up it's
- user interface, or you can get it to do most of it's things from the
- command line.
-
- THE USER INTERFACE
-
- The user interface is very straightforward so I will only touch on it
- lightly here.
-
- When you run PSX with no arguments, a window will open with gadgets along
- the left side, and a scrolling list on the right side. The scrolling list
- contains the names of all the public screens currently in the system, and
- the gadgets on the left are various ways of maniuplating items in the list.
-
- To select a screen, simply click on it's name. The name of the last
- selected screen is just below the list.
-
- "Open Screen" will pop up another window with screen selection gadgets -
- type in the name you want for your new screen, if you want it to be
- hires, etc., click on the appropriate gadgets, then click Open Screen
- (or Cancel if you get cold feet).
-
- "Close Screen" will attempt to close the screen. Public Screens are
- supposed to be closed by the program that owns them, so this is usually
- only a good idea to perform on screens you have opened with "Open Screen".
-
- "Move To Screen" will move the PSX window itself to the selected
- screen. If the screen is LORES, PSX may have a hard time squeezing
- itself onto the screen, but otherwise it should have no trouble dealing
- with whatever fonts and colours the screen has up.
-
- "Make Default" will make the selected screen the "Default Public Screen" -
- which simply means that any program smart enough to open on the
- "Default Public Screen" will now open on that ascreen.
-
- "Refresh List" just grabs a new copy of the screen list, since it won't
- automatically notice if a screen appears or disappears while the
- window is open.
-
- The next two gadgets are "Global Flags" that affect the operation of all
- public screens. The "Shanghai" flag, when on, will redirect all windows that
- would have gone to the "Workbench" screen to the "Default Public Screen",
- and the "PopPubScreen" flag will bring to the front any public screen as
- a window opens on it.
-
- THE COMMAND LINE
-
- Typing "PSX ?" will give you this:
-
- OPEN/K,CLOSE/K,DISPLAYID/K,HIRES/S,LACE/S,DEPTH/N,MAKEDEFAULT/K,SHANGHAI/S,
- NOSHANGHAI/S,POP/S,NOPOP/S,TOFRONT/K,TOBACK/K
-
- and in that line is everything you need to know about PSX's command line
- interface. The keywords are:
-
- OPEN "ScreenName"
- CLOSE "ScreenName"
- DISPLAYID 0x00000000 (display ID number, 0x#=Hex, otherwise Decimal)
- SHANGHAI
- NOSHANGHAI
- POP
- NOPOP
- TOFRONT "ScreenName"
- TOBACK "ScreenName"
- MAKEDEFAULT "ScreenName"
-
- The HIRES and DEPTH items are flags for the OPEN command (ie,
- OPEN "ScreenName" HIRES LACE will open a hires interlaced screen. The
- depth is specified as DEPTH 3 where 3 is the number of bitplanes the
- screen is to have. MAKEDEFAULT specifies that the newly opened screen
- should also become the Default Public Screen.
-
- SHANGHAI and NOSHANGHAI turn the Shanghai flag on and off. These get
- processed AFTER the "Open" and "Close" commands.
-
- POP and NOPOP turn on and off the POPPUBSCREEN flag - enable and disable
- the popping to the front of any screen whenever a window is opened.
-
- So a valid command line would be:
-
- PSX OPEN "CLIScreen" HIRES LACE DEPTH 1 MAKEDEFAULT "CLIScreen"
- SHANGHAI POP
-
- which would give you a screen entitled "CLIScreen", Hires interlaced,
- (with the actual dimensions taken from your preferences), and the SHANGHAI
- and POPPUBSCREEN flags are both turned on.
-
- This in combination with the fact that under 2.0 you can give a Public
- Screen name for console windows to open up on means you can set up a
- screen for the exclusive purpose of running a CLI or two on, making them
- one bitplane so they scroll more quickly than the Workbench screen,
- which would look kind of ugly in one bitplane.
-
- Remember that all public screen names ARE case sensitive - "MyScreen" is
- not the same as "MYSCREEN".
-
- THE SOURCE
-
- I've included the source to PSX. It's a very "2.0" program - it uses
- the DOS "ReadArgs" call to parse the command line, it uses GadTools for
- the user interface, and (I believe) is a good example for dealing with
- public screens.
-
- It compiles with the Lattice 5.10 C compiler and the 2.0 includes. It
- will probably only compile with Lattice, as I've taken a liking to the
- C++ comment style, which Lattice permits.

- AUTHOR AND DISTRIBUTION INFORMATION
-
- PSX is freely redistributable, but is also Copyright 1990 Steve Tibbett.
- Distribution is only very slightly limited: You may not distribute
- PSX without it's current documentation, nor without source,
- and if it is to be commercially distributed, I won't demand but I would
- appreciate being sent a copy of whatever it is being distributed with
- or on (in the case of disk magazines).
-
- Like all my stuff, PSX will likely continue to change. If you like
- PSX, check with wherever you got it every few months for updated
- versions, especially if you have problems with it (and have let me
- know about them), as I normally fix problems quickly.
-
- I don't ask for any cash contribution for PSX. If you are feeling
- guilty and just want to send something, send an original game or
- a neat demo, I'll probably appreciate it more than cash.
