Appendix for Explosiv 2.10
Explanation of Command Line Switches
and Display Parameters for DOS version
This is the entire list of options supported by version
2.0 of the Explosiv screen saver. The interface was
designed so that you will never have to know or use the
majority of these options. However, they are all
listed here for reference. The options that are useful
to know are:
Explosiv ; run the interface
Explosiv - ; read the configuration file
Explosiv on ; activate (normal, herc=text)
Explosiv +on ; activate (animate,
herc=graphics 0)
Explosiv -on ; activate (blank,
herc=graphics 1)
Explosiv remove ; remove the tsr
all the other options can be and should be controlled
by the interface. A complete list of options is listed
below:
aranea - Show the named display. Use the delay factor to
slow the drawing and object level to increase the number
of points drawn.
blank - This is the only display that does not halt the
underlying program when it is resident. The delay factor
and object variable have no meaning. No mouse support
is given to this display if it is resident.
chaos - Show the named display. Use the delay factor to
slow the drawing and object level to increase the number
of lines drawn.
clock - This display is the only non-graphical display in
Explosiv. For this reason it will be used whenever the
video card is an mda. In fact, if an mda card is used
then blank and clock are the only valid displays. All
other displays except blank revert to the clock. Although
a delay factor is not used an object level of 1 does
signify that you wish the clock to be drawn with the
standard rather than extended ascii character set.
discus - Show the named display. Use the delay factor to
slow the movement of the image.
fireworks - Show the named display. Use the delay factor
to slow the drawing and the object level to increase
the number of fireworks drawn at one time.
flow - Show the named display. Use the delay factor to
slow the drawing.
gyro - Show the named display. Use the delay factor to
slow the image and the object level to specify whether
you want one specific object or a random selection.
ifs - Show the named display. Use the delay factor to
slow the drawing and the object level to increase the
number of points drawn.
linus - Show the named display. Use the delay factor to
slow the drawing. This display has the normal delay
level. If an object level of one is given then two
moires are drawn each in its own corner. If an object
level of 2 is given then four moires are drawn in its
own corner. If an object level of 3 is given then four
moires are drawn, two will be in corners and two will
be shifted closer to the center. If an object level of
4 is given then 8 moires are drawn. If an object level
of 5 is given then 12 moires are drawn. If an object
level of 6 or more is given then 16 moires are drawn.
maze - This display uses the normal method of using the
delay factor. The object variable has no effect.
orchid - This display uses the normal method of using the
delay factor. The object level relates to how many
points will be drawn.
random - This display has two different types of randomizing
the displays. If the all parameter is not given then
this display will randomly load a display when Explosiv
is initially run. You will not be able to change this
display until you remove and reinstall Explosiv. The
second type of random is used when the all parameter
is given. Then all displays ( except blank, clock and
stars ) are loaded. Each time the screen saver becomes
active a different display will be used.
ricochet - This display uses the delay factor normally.
The object level has no effect.
serinde - This display uses the delay factor normally.
The object level specifies how many points should be
drawn.
stars - This display does not use the delay factor. The
object level controls how many stars are drawn.
trees - This display uses the delay factor normally. The
object level specifies how many secondary branches
should be drawn. That is, how many branches should
connect to the trunk of the tree.
on - This option will turn the screen saver on. If the
monitor is hercules then this also tells the screen
saver to restore the screen to text mode. If the monitor
is not hercules then this tells the screen saver to
use the animation when possible and to blank the screen
when it feels that the screen cannot be saved properly
( for example, in graphics modes ).
+on - This option will turn the screen saver on. If the
monitor is hercules then this also tells the screen
saver to restore the screen to graphics mode ( page 0 ).
If the monitor is not hercules then this tells the
screen saver to use the animation when possible and not
to screen save then it feels that the screen cannot be
saved properly ( for example, in graphics modes ).
-on - This option will turn the screen saver on. If the
monitor is hercules then this also tells the screen
saver to restore the screen to graphics mode ( page 1 ).
If the monitor is not hercules then this tells the
screen saver to blank the screen under all possible
circumstances.
off - This option will turn the screen saver off.
+video - This option tells the screen saver that it
should check for screen writes through bios. Any
character that is written to the screen will reset the
screen saver's timer.
-video - This option tells the screen saver that it
should not check for screen writes through the bios.
Any character that is written to the screen will not
reset the screen saver's timer. This option should be
used if you are using some sort of RAM resident clock.
all - This option is used to load all the displays, except
blank, clock and stars into memory. You may then change
the display at any time without reinstalling the screen
saver. See the section on random for more details.
Using this option adds about 12K to the resident screen
saver size.
mono - This option specifies that the display should be
in monochrome.
color - This option specifies that the display should be
in color.
d<n> - This option specifies the delay factor that should
be used if required. Here <n> is a number from 1 to
255. By default, Explosiv will check your CPU and
generally deduce the proper delay factor. This option
should only be used if you find the default unreasonable.
Run the command
Explosiv ?
to find the default delay for your CPU.
m<n> - This option must be used if Explosiv is to become
a screen saver. Here <n> ranges from 1 to 30 and
refers to how many minutes of inactivity Explosiv
should wait before activating.
e<n> - This option specifies the object level. This
value ranges from 1 to 9 where the default is 4. Not
all displays use this option and those that do not
always use it in the same way. See above for details.
? - This option will display the help screen. This will
give you information such as hot keys, Explosiv direc-
tory, monitor type, delay factor, multiplex number and
some simple options to use.
- - This option specifies t
