POKE

Description

Store a number at a specified memory location.

Syntax

n = POKE([DataType, ] address, DataValue)

Returns

Number, the passed numeric expression

Parameters

Name	Type	Optional	Meaning
DataType	Command	Yes	Optional parameter indicating the numeric data type to retrieve, which can be one of the following data type: BYTE WORD DWORD INTEGER LONG QUAD SINGLE DOUBLE EXT CUR If no data type is specified, BYTE will be assumed.
Address	Numeric	No	A valid 32-bit memory address specifying the location in memory where data retrieval should begin
DataValue	Numeric	No	The data value to be stored at address

Remarks

POKE provides the functionality of a dynamic pointer: the datatype parameter specifies the data type and also the size of the target data to write to the target memory address.

Datatype can be any one of BYTE, WORD, DWORD, INTEGER, LONG, QUAD, SINGLE, DOUBLE, EXT, CUR.

It is the programmer’s responsibility to ensure that POKE does not overrun the target memory area to avoid data corruption or protection faults.
