Restriction: The TraceChild
parameter is only supported when debugging on OS/2.
@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.
