Record-Display Commands

After PTrace has selected records according to current selection criteria and formatted

them according to current formatting parameters, it sends them to the specified output

device. The FIND, NEXT, and RECORD commands are used to begin PTrace output.

Using the FIND Command to Search For a String

The FIND command examines formatted records for the presence of the character

string you specify. Issuing the FIND command with a character string initiates a search

at the first data record in the file. Also, you can issue a FIND command that restricts

the search to a specific range of record numbers. The first record that meets the

record-selection and filter-selection criteria and that contains the string is displayed.

Issuing the FIND command with no character string initiates a search for the previously

specified string at the record following the current record. The next record that contains

the string is displayed.

If the trace collector cannot keep up with the subsystem process trace, records can be

skipped over (or missed). In this case, a Frames missed message is recorded in the

trace file. You can use the FIND command to detect the missed frames (records).
