Use the TRACE command to control (turn on and off) trace points in your product. When you turn on a trace point, the system considers the trace point to be active and stores information for trace point in the trace file.
Refer to OS/2 Warp Version 4 Command Reference for information about using the TRACE command and its parameters.
The following two statements need to be added to your CONFIG.SYS file before you use the TRACE command:
TRACEBUF=x
If neither statement (TRACEBUF nor TRACE) is included in the CONFIG.SYS file on your system, trace is disabled.
