It will usually be left blank to indicate default reporting to the terminal/batch log file. Options include:
F - Specifies full reporting of task/module entry. L - Specifies duplicate log of reports to disk file (ECH_REPORT.LOG in the current directory). B - Brief reporting, task starts only. S - Silent, no terminal reports at all. E - Error reports to override other setting (BS). P - Print log file on completion (only with L).
Specifiers may be concatenated in any order, thus
would specify minimal reporting, except for task startup and error reports. Reports to be copied to a log file and printed upon completion.
Initial suggested value: ' '.
