Use the 

gosub

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

mation, refer to Labels. The syntax of the gosub statement is:

gosub label_name
...
label_name:

...

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

label_name

.

Also, the calling point is remembered. Upon encountering the 

return

statement,

program execution will continue with the next statement (line) after 

gosub

. The

gosub line can come before or after the label.

It is not possible to jump into or out of routine by means of gosub. Never jump into
a loop or other structured statement, since this can have unpredictable effects.

Note: Like with 

goto

, the use of 

gosub

statement is generally discouraged. mikroBasic

PRO for AVR supports 

gosub

only for the sake of backward compatibility. It is better to rely

on functions and procedures, creating legible structured programs.
