Use the goto statement to unconditionally jump to a local label — for more informa-
tion, refer to Labels. The syntax of the goto statement is:

goto label_name

This will transfer control to the location of a local label specified by 

label_name

. The

goto line can come before or after the label.

Label and 

goto

statement must belong to the same block. Hence it is not possible

to jump into or out of a procedure or function.

You can use 

goto

to break out from any level of nested control structures. Never

jump into a loop or other structured statement, since this can have unpredictable
effects.

The use of 

goto

statement is generally discouraged as practically every algorithm

can be realized without it, resulting in legible structured programs. One possible
application of the 

goto

statement is breaking out from deeply nested control struc-

tures:

for i = 0 to n

for j = 0 to m

...
if disaster

goto Error

end if
...

next j

next i
