ITRAPPER keyword, values: TraceChild [ ON | OFF]
This parameter controls whether ITRAPPER can detect exceptions in the children of the program being traced. By default this parameter is on, and all descendant processes are monitored for exceptions. You only need to turn it off if you are running ITRAPPER against a program that uses the DosDebug() API, because ITRAPPER will cause such programs to malfunction if TraceChild is on.
