Adam Sampson	3122c71eb2	Fix high core purification. ... The PURIMP routine splits the page map into three parts: writable data at the bottom, a large gap in the middle (which the GC will manage later), and read-only code/data at the top. There's one CORBLK call for each of these. The final call, which gave pages BOT/2000 to 400 as the range, failed with %EROPG when it hit the first unmapped page after the end of the pure data. Experimentation shows that, at least with current ITS, this is how CORBLK normally behaves. Fix by calculating the final page from RHITOP rather than assuming 400.	2018-04-25 20:47:04 +01:00
Adam Sampson	b1f3c13826	Disable PURIMP's last call to CORBLK. ... This is trying to make pages from BOT to the end of memory pure, but it fails on current ITS, even if you adjust the end of the range to match RHITOP.	2018-04-25 09:32:25 +01:00
Adam Sampson	414c665700	Fix TVBASE assertion. ... This is checking whether the transfer vector has overflowed the compile-time space allocated for it -- but the test is backwards, so the .LOP .VALUE always fires.	2018-04-25 09:32:25 +01:00
Adam Sampson	32def4d04b	Only add NTTYPE and CLRSTR to the squoze table on TENEX.	2018-04-25 09:32:25 +01:00
Adam Sampson	5a75505e8b	Avoid collision with .FATAL, DMOVE and DMOVEM. ... Newer MIDAS defines all of these itself; Muddle wants its own definitions.	2018-04-25 09:32:25 +01:00
