A Programmed GTO Instruction
The GTO label instruction (press
¹
r
label) transfers the execution of a
running program to the program line containing that label, wherever it may be.
The program continues running from the new location, and
never automatically
returns to its point of origination, so GTO is not used for subroutines.
For example, consider the "Curve Fitting" program in chapter 16. The
instruction branches execution from any one of three independent initializing
routines to LBL Z, the routine that is the common entry point into the heart of the
program:
Can start here.

Using GTO from the Keyboard
You can use
¹
r
to move the program pointer to a specified label or line
number
without starting program execution.
