wanweibaike PEEK and POKE
In computing, PEEK and POKE are commands used in some high-level programming languages for accessing the contents of a specific memory cell referenced by its memory address. PEEK gets the byte located at the specified memory address.[1] POKE sets the memory byte at the specified address.[2] These commands originated with machine code monitors such as the DECsystem-10 monitor;[3] these commands are particularly associated with the BASIC programming language, though some other languages such as Pascal and COMAL also have these commands. These commands are comparable in their roles to pointers in the C language and some other programming languages.
