Mem-Handler is a handler that allows any area of system memory to be
accessed like a file. As an added bonus MEM: will act like NULL: if
no address/length is specified. All writes automatically succeed.
Mem-Handler is Copyright 1990,1991 by Michael Mounier.
Non-commercial distribution is allowed.
Version 1.2 implements some more packet types that seem to be
required for correct operation under that latest version AmigaDOS 2.0
(37.74).
To install Mem-Handler
----------------------
1) Place the following entry in your MountList:
/* MEM:addr/len allows system memory as a file */
MEM: Handler = L:Mem-Handler
Stacksize = 2000
Priority = 5
Globvec = -1
#
2) Copy Mem-Handler to L:
3) Mount MEM:
To access MEM:
--------------
Use MEM:address/length wherever you would use a filename. Address and
length are in HEX.
Examples/Uses
-------------
To look at ROM try:
> Type MEM:FC0000/40000 opt h
You could use MEM: in conjuction with an editor (such as CED) and
AREXX to allow you to compile (or do some other processing) straight
from ram.
You can use MEM: like NIL: or NULL: for example:
> Copy #? to MEM: all
Caveats
-------
You CAN crash your machine with MEM: by reading an area of memory
that contains write only registers.
Avoid the following address ranges:
A00000-BFFFFF
D80000-EFFFFF
