Abstract: There is described a method of compiling source code for a computer program into corresponding object code. The source code includes several declared variables. The method comprises, for each declared variable in the source code, including in the object code a declaration statement indicating an associated memory location for that variable and indicating the position in the object code of the next declaration statement. During compilation, the memory location for each declared variable can be retrieved from the object code by examining each declaration statement in turn, using the position information from each declaration statement to locate the next declaration statement. This is of particular advantage where the available volatile memory is limited, because there is no requirement for a look-up table of variables against memory locations.
