The LOG command creates a log file of all GDE commands and displays for the current editing session. Because the system places an exclamation point (!) (i.e., the comment symbol) before all display lines that are not entered by the user. In the log, the log can be used with the @ symbol as a command procedure.

The format of the LOG command is:

LOG
LOG -ON[=file-name]
LOG -OF[F]

The LOG command, without a qualifier, reports the current status of GDE logging. The LOG command displays a message showing whether logging is in effect and the specification of the current log file for the GDE session.

The log facility can be turned on and off using the -ON or -OFF qualifiers any time during a GDE session. However, GDE closes the log files only when the GDE session ends.

The -ON qualifier has an optional argument of a file, which must identify a legal UNIX file. If LOG -ON has no file-argument, GDE uses the previous log file for the editing session. If no log file has previously been specified during this editing session, GDE uses the default log file GDELOG.LOG.

Example:

GDE> log -on="standard.log"

This command turns on logging of the session and directs the output to standard.log.
