DLG
Break into the console dialog mode. This interrupts your script execution. You can type commands in the command? box, look at the log or choose to exit or continue script execution. All S_TOOLS-STx commands can be entered in the command? edit field except for the control commands IF, GOTO, EXIT, BREAK, CONTINUE, END and all loop commands. All CON commands can be used in the command? edit field without their CON prefix (e.g CLS instead of CON CLS). The button Continue leaves the BREAK mode and continues script execution. The button Clear clears the log text. The button Exit exits the script. The close button has the same effect as Continue.
You can also break into the console using the hotkey combination Ctrl+B.
