Suppress warning messages listed by tag name.
Suppress the display of warning messages specified in the comma–separated list of tag names taglist. If %all, suppress all warnings, which is equivalent to the -w option. If %none, no warnings are suppressed. —erroff without an argument is equivalent to —erroff=%all.
Example:
f95 -erroff=WDECL_LOCAL_NOTUSED ink.f
Use the -errtags option to see the tag names associated with warning messages.
