Jeepers - that is truly f*cked. I've even used the linker script to generate absolute symbols for the sizes of items - they really don't want relocating (ever). If you go back to (say) RSX11/M loads of the constants (like system call numbers and structure offsets) would be supplied by the linker if the assembler didn't know the value. That linker supported (more or less) arbitrary expressions in fixups. David
