Log and Logappend

Specifies the filename of the file to which Gdxxrw write information about its performance.  When omitted, this information will be written to the computer standard output location (usually the screen).  When using Gdxxrw in a GAMS model that is executed from the IDE, the output will be written to the IDE process window.  Using LogAppend will cause the information to be appended to the end of the named file, while Log will overwrite the file.  The syntax is

Log = FileName

LogAppend = FileName

where the filename must be valid on the computer and by default will be placed in the working directory.
