stopstopStopStopstop (Operator)

Name

stopstopStopStopstop — Stop program execution.

Signature

stop( : : : )

Herror stop()

Herror T_stop()

void Stop()

static void HWindow::Stop()

static void HOperatorSet.Stop()

static void HWindow.Stop()

def stop() -> None

Description

The stopstopStopStopStopstop operator stops the continuous program execution of the HDevelop program. If this happens, the PC remains on the stopstopStopStopStopstop statement (instead of being placed at the next executable program line) to show the reason for the program interruption directly even if numerous comments or other non-executable program lines follow.

The operator is equivalent to the Stop action (F9) in the menu bar. Unless parallel execution is used (via the par_start qualifier), the program can easily be continued with the Run action (F5). See also “Parallel Execution” in the HDevelop User's Guide.

It is possible to redefine the behavior by setting a time parameter in the preferences dialog. In this case, the execution will not stop but continue after waiting for the specified period of time. Within this period of time, the program can be interrupted with F9 or continued with one of the run commands. This is marked by an icon in the first column of the program window.

Attention

This operator is not supported for code export.

Trying to continue a program that uses parallel execution after calling stopstopStopStopStopstop may cause non-deterministic thread behavior or errors.

Example (HDevelop)

read_image (Image, 'fabrik')
regiongrowing (Image, Regions, 3, 3, 6, 100)
count_obj (Regions, Number)
dev_update_window ('off')
for i := 1 to Number by 1
  select_obj (Regions, RegionSelected, i)
  dev_clear_window ()
  dev_display (RegionSelected)
  stop ()
endfor

Result

If the program stops at a stopstopStopStopStopstop statement, the return state of the previous operator is kept. If the program is continued with the stopstopStopStopStopstop operator, stopstopStopStopStopstop always returns TRUE.
