Paging? The conventional wisdom has always been to stay within one base register,
The XPL compiler used multiple base registers.
so for systems with 4K pages that isn't an issue. I tend to use LOCTR so that constants aren't always at the end of the source code. I normally put labels on the same line as the instructions and inserting code has never been a problem. I will admit to using self-modifying code when I was a callow youth, but I stopped doing that and started making any new code reentrant and refreshable sometime around the end of the 1960s.
