Description

dev_update_pcdev_update_pcDevUpdatePcDevUpdatePcDevUpdatePc specifies the behaviour of the PC during program execution. If DisplayModeDisplayModeDisplayModeDisplayModedisplayMode is set to 'on'"on""on""on""on", which is the default, within the selected procedure the PC is always displayed left to the currently executed operator. In addition the program text is scrolled---if necessary---so that the current operator is visible.

If the mode is 'off'"off""off""off""off" the PC is not visible during program execution and the program text will not be scrolled automatically. When the program stops the PC becomes visible again and the listing is scrolled to the current PC position.

For measuring the execution time of a sequence of operators all update options should be switched off in order to reduce the influence of the runtime of GUI updates in HDevelop. For this the operators dev_update_pcdev_update_pcDevUpdatePcDevUpdatePcDevUpdatePc, dev_update_timedev_update_timeDevUpdateTimeDevUpdateTimeDevUpdateTime, dev_update_vardev_update_varDevUpdateVarDevUpdateVarDevUpdateVar, and dev_update_windowdev_update_windowDevUpdateWindowDevUpdateWindowDevUpdateWindow or the procedures dev_update_on and dev_update_off can be used.

This option can also be controlled via the Preferences dialog: Edit -> Preferences -> Runtime Settings -> Update Program Counter.
