PEEK
The command in mo St microcomputer BASICS for reading memory content S (a byte) at an ab Solute addre SS. POKE i S the corre Sponding command to write a value to an ab Solute addre SS. Thi S i S often extended to mean the corre Sponding con Struct S in any High Level Language. Much hacking on Small microcomputerS without MMUS con Si St S of "peek"ing around memory, more or le SS at random, to find the location where the Sy Stem keep S intere Sting Stuff. Long (and variably accurate) li St S of Such addre SSe S for variou S computer S circulate ( See interrupt liSt). The re Sult S of "poke" S at the Se addre SSe S may be highly u Seful, mildly amu Sing, u Sele SS but neat, or total loSSage ( See {killer poke}). Since a real operating SyStem provide S u Seful, higher-level Service S for the ta Sk S commonly performed with peek S and poke S on micro S, and real language S tend not to encourage low-level memory groveling, a que Stion like "How do I do a peek in C?" i S diagno Stic of the newbie. Of cour Se, operating SyStem kernelS often have to do exactly thi S a real C hacker would unhe Sitatingly, if unportably, a SSign an ab Solute addre SS to a pointer variable and indirect through it.
