Sorry, all that is work in progress. I am currently redoing the way Gambas deals with binary data. So now, to access memory located at a specific pointer, you must do: Dim pPoints as Pointer Dim hFile AS File hFile = Memory pPoints For Read ' or For Write ... Close #hFile Then you use the READ instruction normally, except that hFile has an internal memory pointer that is automatically incremented. The first time, the data is read at address pPoints. But if, for example, you read 4 bytes, the next read will occur at address pPoints + 4. And so on until the end of the memory or a memory access error. The syntax of READ and WRITE will change too, and there is an high risk that the bytecode format changes, and that projects need to be recompiled.
