in use, PTrace closes it before opening the new one.

is a trace file.
Considerations: FROM Command
•
When the FROM command is used, PTrace automatically invokes the
STATETABLES command. The subsystem associated with the trace file specified
in the FROM command determines which state-machine file name is used by the
STATETABLES command. The state-machine file name that PTrace looks for is
$SYSTEM.SYSnn.ZxxxSMT where xxx is the subsystem name abbreviation
listed in the SPI Programming Manual. If this file cannot be accessed, no error
message is issued.
?F B "File" Finds the first instance of any string consisting of the
uppercase or lowercase letters f, i, l, e.
?FIND Finds the next instance of the string specified in the
previous FIND command.
?F B "miss" 100,300 Finds the first instance of any string consisting of the
uppercase or lowercase letters “m, i, s, s” (in that
order) within records 100 through 300.
?FIND A “test” 1/230 Finds all instances of the string “test” within records 1
