GOTO _ _ _ _ _ _ _ _ _ _ _ _ command
Inside a begin...end block, goto, or preferably, go to, transfers flow of control to a labeled statement.
go to<labeled_statement> or goto <labeled_statement >
<labeled_statement> is of the form <label> :<statement >
procedure dumb(a); begin scalar q; go to lab; q := df(a**2 - sin(a),a); write q; lab: return a end; DUMB dumb(17); 17
go tocan only be used inside a begin...end block, and inside the block only statements at the top level can be labeled, not ones inside <<...>>, while...do, etc.
