Unconditional branching uses the GTO (go to)instruction to branch to
a program label. It is not possible to branch to a specific line number
during a program.
MtiHQ] label
A Programmed GTO Instruction. The GTO label instruction trans
fers 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 it does not ever automatically re
turn to its point of origination, so GTO is not used for subroutines.
For example, consider the 'Curve Fitting* program on page 204 in
part 4. The GTO Z 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:
S01 LBL S
S05 GTO Z
L01 LBL L
L05 GTO Z
E01 LBL E
E05 GTO Z
Z01 LBL Z
Using IH"gto1 From the Keyboard. If program entry is not active
(no program lines displayed; PRGM off), then you can use 111 gto Ito
move the program pointer to a specified label or line number without
starting program execution.
• To a label: HrGTOl label (Example: Hdjo] A .)
• To a line number: Sll gto I(T) label nn (nn < 100. Example:
1(GTO)(I|A05.)
• To PRGM TOP: BCHESE!
