Inner Mission -- A deep space screen saver
COPYRIGHT (C) 1990 KEVIN STOKES
Description:
------------
Inner mission is a program which occupies the video monitor with a
relaxing view of stars floating past. The program has many options so
that the user may adjust the speed, and number of stars, etc. It can
be loaded into memory as a TSR, or run directly as a normal program.
If loaded as a TSR, the program may be set to pop-up with a hot-key, or
automatically after an adjustable period of cpu idleness. There are many
options designed to keep the TSR from interrupting when it is not desired.
There are also some fun special effects possible, including hyperspace,
time & date written in stars, and user messages (you type in when IM first
loaded) which float past at various time intervals.
There are two versions of the program, IM.EXE and IMS.EXE. They are
very similar, but IMS occupies less than half the memory space at the
expense of the text features. This is for users who have limited memory
space available for TSR's. (If you are one of these people, note the -E & -Z
option.)
Behavior:
---------
When the program is executed, it gives a signon message, and then
returns to DOS, having left part of itself in your computer's memory.
If you leave you computer idle for more than a few minutes, Inner Mission
will automatically popup, giving a relaxing view of a travel through space.
When the user returns to the computer, touching the shift key, or the space
bar will return the computer its original state.
The program may also be popped up manually through typing a combination of
hot keys. (For example the usual case is holding down both shift keys)
Since the program is designed as a screen saver, (prevents characters from
being burned into the phosphor of your monitor) Inner Mission will also
blank the screen if the machine is left untouched while it is busy. This
is just a blank screen, and no stars show in this case because the stars
display would interrupt the busy program. When the screen is merely blanked
there is no halting of the progress of the original program. Again, a tap on
the shift key will return the computer to its original state.
Even though the Inner Mission program is already loaded into memory, you
may change various parameters (such as # of stars) merely by typing IM with
new options selected. The program will find itself in memory, and cause the
new parameters to be implemented.
System Requirements:
--------------------
Inner Mission requires an IBM or compatible PC/XT/AT/386 with a video
graphics card compatible with CGA, EGA, MCGA (PS/2), Hercules, or VGA.
Revision History:
-----------------
Version 1.5 was the first version released to the public.
Version 1.6 has the following changes and additions:
The options can now be set from a menu, as well as by the command line.
The menu will appear if there are no options on the command line.
Hercules compatible monochrome graphics cards are now supported.
Bug fixed in IMS where the screen wouldn't save properly.
The font of the float-past characters can now be changed. See Pie.bat for
an example.
The speed of the stars can now be changed with the keypad +- keys while the
stars are popped up. The speed may be changed while text is floating past.
IM now detects the trapping of int 9, and will not pop up if another program
has trapped it.
The default for serial¶llel ports has been changed to no checks. The
code for this has been made more streamlined.
Version 1.7 has the following changes and additions:
Removal of keyboard interrupt bug.
Stars are no longer repeat. As each star passes by, a new star takes its
place. On previous versions, the star simply repeated the same trajectory
over and over.
