wink The command in most {
microcomputer } {

for reading
memory contents (
a byte )
at an absolute address .
POKE is the
corresponding command to write a value to an absolute address .
This is often extended to mean the corresponding constructs in
any {
High Level Language }.
Much hacking on small {
microcomputers }
without {
MMUs }
consists
of "
peek "
ing around memory ,
more or less at random ,
to find
the location where the system keeps interesting stuff .
Long
(
and variably accurate )
lists of such addresses for various
computers circulate (
see {
interrupt list }).

"
poke "
s at these addresses may be highly useful ,
mildly
amusing ,

Since a {

provides useful ,
higher -

on micros ,
and real languages tend not to encourage low -

a question like "
How do I do a peek in C ?"
is diagnostic of the {
newbie }.
Of course , {
operating system }
{

often have to do exactly this ;
a real {

would unhesitatingly ,
if unportably ,
assign an absolute
address to a pointer variable and indirect through it .
