Add layer of indirection to EMIT This would allow things like temporary giving control to the CL line on the TRS-80. For example... A very far fetched example. Not at all the only raison d'etre* of the layer... 2020-05-02 10:05:15 +10:00			`CURRENT @ 0x2e RAM+ ! ( 2e == BOOT C< PTR)`
Stop LOADing on ABORT This is done by adding a "C<* override" layer that is reset to 0 on ABORT. The problem was that when ABORT happened during a LOAD, we had a resetted RSP and started from a clean INTERPRET, but LOAD didn't have the opportunity to restore C<, which caused it to continue interpreting from the faulty BLK. With a C< override, we don't need to restore C<*, we just need to clear the override. 2020-04-25 04:10:40 +10:00			`0 0x08 RAM+ ! ( 08 == C<* override )`

Replace the "> " prompt with the more traditional "ok" one This is more than cosmetic, it's also highly usable. The presence or absence of the "ok" message allows us to know whether the command aborted. Previously, the "> " prompt appeared when the system expected a prompt in the INTERPRET context, whether the previous command aborted or not. Also, this allows us to get rid of that ugly FLAGS global variable. 2020-04-25 02:10:07 +10:00			`( 0c == C<* )`
