| Syntax | HALT HALT id HALT id id id ... |
| Explanation | HALT stops the execution of all running
background procedures. Optionally, HALT may be given as
input(s) the ID number(s) of the procedure(s) to be
stopped. The ID number is reported by LAUNCH when a
procedure is activated. See also LAUNCH. |
| Examples | The procedure below will send turtle 1
to random locations on the screen. If this procedure is
launched as a background procedure, the turtle will creep
along the screen while allowing you to enter commands and
run other procedures. Note that the procedure does not
use the TELL command, because this command alters the
TELL list which is used by all Logo procedures. TO
