Use this command to start the selective file trace (SFT) debugging tool. The SFT debugging tool monitors the updating of selected file addresses during a specified trace period.
Use the SFT debugging tool and the selective file dump (SFD) debugging tool (also referred to as the selective file dump and trace (SFDT) debugging tools) to locate file-related errors during online operations or while testing under the control of the program test vehicle (PTV) utility.
Requirements and Restrictions
None.
Format
|
You can specify up to 43 fields with one command. The number of records specified in a single command cannot exceed 420.
Additional Information
All output from the SFDT debugging tools is written to the real-time tape (RTL/RTA). SFD and SFT output may be interspersed with other test or control program output also on the real-time tape. Use the offline diagnostic output formatter (DOF) utility to process the SFDT output. See TPF Program Development Support Reference for examples of the SFDT output.
