Description
var
ByRef
any variable
The variable of which the address is desired.
Discussion
This function returns the UnsignedInteger 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 DataAddress property may also be used to determine the address of a variable (except in BasicX
compatibility mode). The type of the resulting value is UnsignedInteger. See the examples below.
Examples
Dim addr as UnsignedInteger
Dim ba(1 to 20) as Byte
Dim fval as Single
addr = MemAddressU(fval)
addr = MemAddressU(ba)
addr = MemAddressU(ba(2))
addr = ba.DataAddress
addr = ba.DataAddress(2)
