nSeconds

Specifies the delay in seconds between execution of each program line. The startup default value is 0, with no pause between execution of program lines. nSeconds can range from 0 to 5.5 seconds. For example, if nSeconds is 0.5 seconds, a 1/2-second delay occurs between execution of program lines.

The Trace window, one of the debugging tools available in Visual FoxPro, displays a program's source code as the program executes. The Trace window highlights each line in the program when the line executes. The numeric value of _THROTTLE determines the delay between execution of each program line when the Trace window is open.

Note:
The Trace Between Breaks option on the Trace window's Program menu must be on for a delay to occur.
