124 Function Summary and Index
{O'to F} Label. programmable (page Conditionals
Used to access
programs (page 73).
Return. Halts
execution of a
running program and
returns position in
program memory to
line 000. If a
subroutine is
running,
merely returns
execution to the line
after the
corresponding
instruction (page
74).
Run/Stop.
Begins or stops
execution at the
current linein
program memory
(page 76).
Pause. Halts
program execution
briefly to display the
X-register contents
(page 75).
label. Transfers
program execution to
the given label. Pro-
grammable (page
87).
(GTO[“] nnn.
Positions the
calculator to the
existing line number
specified by nnn. Not
82).
label. Goto
subroutine. Within a
program, this
transfers execution
to the given
subroutine, which
returns execution to
the body of the
program when a
instruction is
encountered. From
the keyboard,[QTB_]
is used to start
execution of a
labeled program
(page 87).
Single step. Pro-
gram mode: moves
calculator forward
one or more lines in
program memory;
scrolls if key is held.
Run mode: displays
and executes the
current program line,
then steps to the
next line to be
executed (page 82).
Back step.
Moves calculator
back one linein
program memory
(will also scroll in
Program mode).
Displays line number
and contents of pre-
vious program line
(page 82).

Flag set? Bit set?
Tests for the flag or
bit specified. If set,
program execution
continues; if
cleared, program ex-
ecution skips one
line before continuing
(page 89).
[x<0],[x>y],
[x=0] Condi-
tional tests. Each test
compares the value
in the X-register
against zero or the
value inthe Y-
register. If the
comparison is true,
program execution
continues; if false,
program execution
skips one line before
continuing (page
88).

Decrement and skip
if zero, increment
and skip if zero.
Decrements or
increments value in
Index register and
skips execution of
the next program line
if the new index
value equals zero
(page 90).
