MEM.COM, written July, 1987, by Doug Cox in 8088
Look at memory (up to 1 meg) on an IBM PC compatible with a monochrome or
color graphics adaptor screen.
Includes the capability to jump to an address, and to find a string of
characters.
Press ESC to quit
Press '?' for help screen
Cursor location (in hexadecimal) and contents are shown at the top of the screen
Arrow keys move the cursor
Ctrl-Left/Right Arrow keys move the cursor 10 spaces left/right
Toggle Scroll Lock ON to scroll screen with Up & Down Arrow keys
Press Home to go to left side of screen
Press End to go to right side of screen
Press Ctrl-Home to go to the top of screen
Press Ctrl-End to go to the bottom of screen
Press PgUp to go to previous screen
Press PgDn to go to next screen
Press Ctrl-PgUp to go to beginning of memory
Press Ctrl-PgDn to go to end of memory
Press Ctrl-F to find a string of up to 8 characters
(beginning from the beginning of memory)
(use the DOS capability of inputting any ASCII character by toggling Num Lock ON
and then pressing the Alt key along with the decimal number representation
of any ASCII character on the numeric key pad. When you release the Alt key,
the graphic representation will be seen after 'Find: ' at the top of the screen
You can thus find a string of any type of character.)
Press Ctrl-L to repeat looking for that string from the current cursor location
Press Ctrl-J to jump to any memory location
(input the address in hexadecimal numbers)
If you would like me to make any changes (like eliminating any screen flicker
when you scroll the screen), you can contact me by modem on the SIGSIG BBS at
(415)968-7369, or at home (415)949-0624, or by mail at 140 Monroe Dr, Palo Alto,
Ca, 94306. Doug Cox
