You really shouldn't be teaching your students using absolute mode. It promotes bad programming, provides no means to allocate RAM, plus other drawbacks. Set them up with a template linker file and tell them to ignore the "linker magic" until they're ready to understand it. Make them learn right from the start that variables are reserved with RES. You can still start out with a single file with one UDATA section and CODEs instead of ORGs, then get more fancy when you teach them about the linker magic later. In the mean time they are no worse off than in absolute mode, but they won't be learning bad habits they have to unlearn later. ******************************************************************** Embed Inc, Littleton Massachusetts, http://www.embedinc.com/products (978) 742-9014.
