Label subtraction was deprecated in version v5 of Specasm and is now removed in v7 to free up space needed for the next opcodes. It's still supported by the linker however, so .x files created with pre v7 versions of Specasm can still be linked with the v7 linker. The Specasm editor will rewrite instructions that use label subtraction to use the new expression syntax when it loads .x files. Signed-off-by: Mark Ryan <[email protected]>

The specasm .dotn file now works properly on the next. This is achieved by relocating some of the code into 3 separate 8kb banks, 2 for the parsing code and 1 for the dumping code. We have about 1.5kb free in the main section. We also fix the keyboard input (for all clockspeeds) and the printing routines which relied on the ROM being mapped and so needed to be rewritten.
