Earlier I posted about a problem running RCA's Basic 3 on my
Basic would run 1 line and stop. I've since recalled that
the old basic's often checked the terminal's BREAK key so
the user could escape a loop. Since the system's serial
comms used /EF4 that was a clue. Basic had to be checking
/EF4 independently of UT62's use of /EF4.
So I whipped up a disassembler and Lo and Behold...

So I restarted the system, held the Elf's Input key,
(which controls /EF4) and ran the Basic program again.
This time it acted correctly, like it did under Emma 02.
There are other B4's and BN4's in the Basic, but I have
left them alone for now.
So some of the mystery solved. perhaps Marcel or Herb might
know something about the other /EF4 branches in there.
Since I am not much of a Basic programmer I ask could someone
post or point me to more basic programs that might use to
