I agree with all of this.

But if meynaf wants to use 'tst.l a7' to save a tiny bit of memory in his code then that's OK. After all, we don't complain about compilers torturing 68k instructions in...

Magic numbers are never good. But do something like 'Z_flag = $04' and the meaning is clear.

Thanks for that. The text manual I have for SASC 6.5 says default length is 255, so I figured something else must be limiting it. Perhaps 255 is actually the maximum.
