use the call statement.

Suppose you have a section labeled "goober:"

The way to "go" there is:

       call goober

At the end of the block labeled goober:
insert the statement "return".  This takes you back to the point from
which goober: was called.

For example:
--------------------------cut here-----------------------------------

/* Test script.  Tests call to a label and return from the label. */

say "You're here..."

call goober

say "You're back!"

exit

goober:

say "Howdy-doody, goober here!"

return
----------------------------------------------------------------------
It's that simple.
