<
programming> (Or "
GOTO", "go to", "GO TO", "JUMP", "JMP") A
construct and
keyword found in several higher-level
programming languages (e.g.
Fortran,
COBOL,
BASIC,
C)
to cause an
unconditional jump or transfer of
control from
one point in a program to another. The destination of the
jump is usually indicated by a
label following the
GOTO
keyword.
In some languages, a label is a line number, in which case
every statement may be labelled, in others a label is an
optional alphanumeric
identifier.
Use of the
GOTO instruction in
high level language
programming fell into disrepute with the development and
general acceptance of
structured programming, and especially
following the famous article "
GOTO statement {considered
harmful}". Since a
GOTO is effectively an
assignment to the
program counter, it is tempting to make the generalisation
"assignment considered harmful" and indeed, this is the basis
of
functional programming.
Nearly(?) all
machine language instruction sets include a
GOTO instruction, though in this context it is usually called
branch or jump or some
mnemonic based on these.
