TRACE
ON filename [ , size ]
starts a trace on the specified unstructured disk file.
The file name should be fully qualified; if it is not qualified, the default volume and
subvolume in effect at the time the NBT application was started are used, not the
defaults from the NBTCOM startup. If the file name does NOT begin with $ or \, the
keyword ON is required.
A file of the specified size will be created. If a trace is already open, it is first closed.
The trace file can specify the same name as an already active trace file. In that case,
the trace file is rewritten. The TRACE RESET command is more efficient for this
purpose.
size
determines the byte length of the trace file. The number can be followed by the
letter K (kilobytes) which multiplies by 1,024, or the letter M (megabytes)
which multiplies by 1,048,576. The default is 100K. The minimum is 12K and
the maximum is 25M.
