The instruction you have used earlier to position the calcula-
tor to a specific program line for viewing or editing is also used to
transfer execution to a label elsewhere in program memory. When
used as an instruction in a program [GTO]is followed by an alpha or
numeric label address.

Instruction
When a running program encounters a label instruction,
execution is suspended while the calculator searches downward in
memory for the specified label. Program execution resumes at the
first line found to contain the label.
Branching and Looping
Unconditional Branching. An unconditional branch is simply
a[GTO]instruction that is always executed in a running program to
transfer program execution elsewhere in the program, regardless of
data status. The preceding illustration of operation is an
unconditional branch.
Conditional Branching. When label is used in conjunction
with a conditional test, as in the following illustration, the
label instruction becomes a conditional branch. That is, the result
of the conditional test preceding the determines whether or
not the [GTO]instruction will be executed.
