Use the 

goto

statement to unconditionally jump to a local label — for more informa-

tion, refer to Labels. Syntax of 

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.

The label declaration, marked statement 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.

Use of 

goto

statement is generally discouraged as practically every algorithm can

be realized without it, resulting in legible structured programs. One possible appli-
cation of goto statement is breaking out from deeply nested control structures:

for (...) do

for (...) do

...
if (disaster) then goto Error;
...

.

.
.

Error: // error handling code
