lf the GO TO, followed by an address (but no page sign), re-
quires program steps on both pages, then the branch will be to
the address on the same page as the GO TO instruction:

the program will go to address (+)58.
'CONTINUE' is used to start program execution at the
present address. Usually a manual operation but may
be used as a 'no operation' program step (see Correct ·
ing a Program , Page 79).
lf the program has halted at a STOP instruction, press CONT to
continue running the program (at the next program step).
lf the program has halted at an END instruction, press CONT
to run the program [ starting at address (
+
)00].
Halts the program and causes a return to the display
mode (see Page 60). Use the STOP instruction in a
program where data has to be entered manually.
When the program is halted, any keyboard operation can be
manually executed without affecting the stored program. lf,
however, the keying sequence used stores data in a register
which contains program steps, the program steps in that regis·
ter will be destroyed.
