problem.setlogfile
| problem.setlogfile | 
  Purpose
 
 
  This directs all Optimizer output to a log file.
 
 
  Synopsis
 
 problem.setlogfile (filename)
 
  Argument
 
 | 
     filename 
     | 
     The name of the file to which all output will be directed. If set to
     None, redirection of the output will stop and all screen output will be turned back on (except for DLL users where screen output is always turned off).
     | 
  Example
 
 
 The following directs output to the file
 logfile.log:
 
 p = xpress.problem ()
p.setlogfile ("logfile.log")
  Further information
 
 
 1. It is recommended that a log file be set up for each problem being worked on, since it provides a means for obtaining any errors or warnings output by the Optimizer during the solution process.
 
 
 2. If output is redirected with
 setlogfile all screen output will be turned off.
 
 
 3. Alternatively, an output callback can be defined using
 problem.addcbmessage, which will be called every time a line of text is output. Defining a user output callback will turn all screen output off. To discard all output messages the
 OUTPUTLOG integer control can be set to
 0.
