1 /LOG
/LOG /NOLOG (D) The /LOG qualifier produces two messages on the SYS$OUTPUT device: the first shows the the name of the form being extracted and the second shows the name of the output form file. If the /NOOUTPUT qualifier is specified along with /LOG, the second message is not printed. The /NOLOG qualifier will disable both messages.
2 /OUTPUT
/OUTPUT[=file_spec] (D) /NOOUTPUT The /OUTPUT qualifier allows you to assign a name to the output form file. The default output file name is the CDD object name of the TDMS form. The default output file type is .FRM. The /NOOUTPUT qualifier can be used to suppress output.
