POKE Statement Details
 
Syntax
  POKE address,byte
 
The expression address is a value that represents the address of the memory
location; address must be in the range 0-65,535.
 
The expression byte is the data byte to be written; it is an integer value
in the range 0-255.
 
The address is treated as the offset from the current default segment (as
set by the DEF SEG statement).
 
If the argument is a single- or double-precision floating-point value or a
long integer, it is converted to a two-byte integer.
 
The complementary function to POKE is PEEK.
 
                           ----- Warning -----
    Use POKE carefully. If used incorrectly, it can cause BASIC or the
    operating system to fail.
