Description
var
ByRef
any variable
The variable of which the address is desired.
Discussion
This function returns the Integer representation of the RAM address of the specified variable. Note that
for arrays, you may also specify subscript expressions for all of the array dimensions to yield the address
of an individual array element. Without the subscript expressions, the resulting value will be the address
of the first element of the array.
This function is useful for deriving the address to pass to the several functions that require a RAM
address, e.g. BitCopy(), RamPeek(), RamPoke(), etc.
The address of any variable can also be obtained using the DataAddress property. For RAM-based
variables, the DataAddress property is of type UnsignedInteger.
Example
Dim addr as Integer
Dim ba(1 to 20) as Byte
Dim fval as Single
addr = MemAddress(fval)
addr = MemAddress(ba)
addr = MemAddress(ba(2))
addr = fval.DataAddress
addr = ba.DataAddress
addr = ba.DataAddress(2)
Compatibility
BasicX only supports the DataAddress property for Program Memory data items.
