the unusual data dump by Jim Webster
------------------------------------
Ever want to see what the insides of yer machine's memory
looks like -- VISUALLY? That's right, no hexidecimals here,
we're talking instantaneous data transfer to yer optical nerves
via pixel express!
MemFlick treats all the memory in yer Amiga like it was part of
a bitplane inside a graphics display. It starts at memory
location zero and works up to 256K, copying the memory contents,
wherever it goes, into its double buffered display memory,
going 40 bytes (one display line) at a time. The effect is like
watching a river of dancing lights gliding up from the bottom
of your screen, before it scrolls off the top.
NOTES ON USAGE:
Run from Workbench by clicking on then MEMFLICK icon, or from
CLI. You may also specify a number of CLI arguments:
MemFlick s<start address> e<end address> j<jump> d<depth>
<mode> <fade> <cycle> <loop>
...where the arguments mean:
start address: a long value, representing the first memory
address that MemFlick uses to stash into its display.
Default = 0. Example:
MemFlick s200000
would run MemFlick with display memory starting at memory
address 200000.
end address: The highest memory address that can be used as
the first byte of the first bitplane of a (the final) frame,
before MemFlick either shuts down or repeats loop. Default
is 256000. Example:
MemFlick e125000
jump: another long value, representing the offset between the
start of this frame's memory location and the previous frame's.
The higher the value, the faster the river will "flow." Default
is 40, which provides a smooth, orderly current; using values
below this will make the flow appear to go from left to right
as well as from bottom to top. Example:
MemFlick j80
will make the river flow twice as fast as default.
depth: number of bitplanes, 1 to 5 (HAM sets to 6
automatically). Example:
MemFlick d3
will produce a display with 8 colors.
mode: only four are recognized: LO-RES (default), HAM,
LACE (interlace) and HIRES (640x400).
fade: will progressively lighten each RGB value until they
reach maximum 15 value, whereupon they start again at zero.
Example:
MemFlick fade
cycle: cycles all colors one time for each frame. Example:
MemFlick cycle
loop: By default, MemFlick ends when it comes to the end
address. By specifying loop, it will loop forever until a
is pressed. Example:
MemFlick loop
Each of these arguments can be supplied in any order, and can
be combined in any way you please. For example,
MemFlick s10000 e20000 j2 d3 HIRES fade
