TRACELOG - Control the trace log file

Syntax:	TRACELOG	[ file name ] \| [ /options ]
Arguments:	[ file name ]	Optional variable or string defining a file or path name; if no path is defined Robo-FTP’s working folder is used.
Options:	/append	Specify that trace data is to be appended to preexisting [ file name ] (if any); if the file does not exist, it will be created.
	/debug	Enables extended debugging messages.
	/maxsize=xx	Specify the maximum size of the trace log file (in Kilobytes).
	/new	Specify that a new trace log file name is to be created (based on the current date and time) when this command is executed and whenever an existing trace log file reaches the maximum size (if a size has been specified).
	/off	Turn trace logging off.
	/on	Turn trace logging on (assuming that [ file name ] has been previously defined on an earlier call to TRACELOG or a log file has been previously defined under the Logging menu of the Robo-FTP Configurator).

The Trace Log file records trace and diagnostic messages that may be helpful in troubleshooting file script failures. You must attach copies of the Script Log and Trace Log showing the problem when you submit a support request asking for help troubleshooting a script or command.

If the [ file name ] argument is present, this script command creates a new trace log file by this name. It is also implied that logging is to be enabled.

The /new option instructs Robo-FTP to create a new trace log file name using the current date and time. Such a file will be created when the command is executed and, if the /maxsize option is also specified, whenever the trace log file exceeds this maximum size. The [ file name ] argument must be present, but it can be an empty string. Robo-FTP takes the base file name (i.e., the part of the file name before any extension) and appends the current date and time in the fashion shown below. Notice that if no extension is originally specified, Robo-FTP appends .log to the final file name.

When the /new option is used the name of any newly created log file is available in the %currenttracelogfile script variable.

The /maxsize option limits the maximum size that a trace log file can grow to. The size is specified in kilobytes. When the maximum size is reached, Robo-FTP handles this condition in one of two ways. If /new is also specified, the current trace log file is simply closed and a new file is created using the convention described above. If /new is not present, Robo-FTP toggles between two files. When the first file is full, it is closed and a second created and written to. When the second file is full, it is closed and the first file is reopened, cleared, and logging continues. This alternating between files continues until Robo-FTP terminates. When /maxsize is present, [ file name ] is altered as shown below. Notice that if no extension is originally specified, Robo-FTP appends .log to the final file name.

The /append option instructs Robo-FTP to append new trace data to a previously existing file specified by [ file name ]. If [ file name ] does not exist, it will created. The /append option may be combined with /maxsize but may not be used with the /new option.

If [ file name ] is omitted, the /on and /off options control logging to a previously defined log file. When logging is turned on, new log messages are appended to the existing log file. For example:
