Pressing the SK_BREAK key displays a 4GL trace at that moment without halting the image. This is useful when an application appears to be caught in an infinite code loop, perhaps due to a logic error. On most keyboards, this SK_BREAK speed key defaults to the Pause/Break key.

When you press Pause/Break, the program outputs the 4GL stack to a location defined by the current –T flag settings of the runtime without stopping the execution of the code.

For more information, see Using the SK_BREAK Key to Output the Currently Executing 4GL Call Stack in the Programming Guide.
