I've checked with my v3.3 manual and found no real change , just some wording difference with "top of RAM" being replaced by "BEGinning of program memory" to emphasize the fact that after a GTO . . the BEG indicator should be ON to indicate that the program counter is at step 000.

So, there are some discrepancies between the 3.3 manual and the 3.3 software:

1. GTO . . doesn't put the program pointer to step 000 as documented, but at the last END of the last program in the RAM
2. out of PRGM mode, GTO .000 doesn't put the program counter at step 000, outside of any program (as it does in PRGM mode) but at step 001 inside the first program
3. the BEG indicator is ON when the program counter is at step 000 as documented in the manual, but also at step 001

For the first item I've found some references in message #5 of this thread and in message #12 of this other thread. Initially GTO . . was designed to behave differently in PRGM mode (go to last END) and out of PRGM mode (go to step 000).
And btw I've learned a new trick not documented in the manual as far as I can see: no need to press h before GTO . as XEQ . will do the same.

The second and third items look to be some minor bugs for me as I can't see why the software would not follow the manual on these points.
