By default, allocate about 0x100 bytes for PSP+RSP During "make updatebootstrap", we use less than 0x20 bytes on the PSP side and less than 0x40 bytes on the RSP one. 0x100 bytes ought to be enough for anybody.

Integrate RDLN input buffer into sysvars In the beginning of Collapse OS' Forth version, the readline sub- system was optional. This is why we had this separate RDLN$ routine and that the input buffer was allocated at boot time. It's been a while since the RDLN system has been made mandatory, but we still paid the complexity tax of this separation. Not anymore.

Move z80a from B200 to B5 The idea is to consider assemblers as "runtime" apps instead of placing them in the "bootstrap" section of the blocks. These apps will be used for much more than bootstrapping. Moved its documentation to doc/asm.txt and made its code blocks more compact.

ti84: offset binary by 0x100 to free space for TI-specific stuff Not yet tried on real hardware, but we should be getting pretty close...
2020-05-10 14:06:01 -04:00
( TI-84+ requires specific code at specific offsets which
come in conflict with Collapse OS' stable ABI. We thus
offset the binary by 0x100, which is our minimum possible
increment and fill the TI stuff with the code below. )
Add words |M and |L Splitting a word into MSB/LSB pairs happens often and is worth, I think, native words. Also, I'm going to need it in the upcoming commits.

0x03 ALLOT0 ( 0x53 )
Make KEY non-blocking ... and rename it to KEY?. Then, add KEY from KEY? for its blocking version. I need this for an upcoming Remote Shell feature. If a Collapse OS system remotely controls another shell, it needs to be able to poll both the remote system and the local keyboard at the same time. A blocking KEY is incompatible with this. In some places, the polling mechanism doesn't make sense, so this new KEY? always returns a character. In some places, I just haven't implemented the mechanism yet, so I kept the old blocking code and added a "always 1" flag as a temporary shim. I have probably broken something, but in emulators, Collapse OS runs fine. It's an important reminder of what will be lost with the new "dogfooding" approach (see recent mailing list message): without emulators, it's much harder to to sweeping changes like this without breaking stuff. It's fine, I don't expect many more of these core changes to the system. It's nearly feature-complete.

grid: add XYMODE In VE on the SMS, the first contents line would always be cleared because of NEWLN being called when the FBUF would spit its last char. Inconvenient... I've added a "graphical" mode to the grid subsystem to inhibit this behavior in a graphical situation such as in VE. Also, write a more complete Grid documentation.
