+# GAWK can provide the invoking program name from ARGV[0] but is unable to
+# provide the AWK script name that follows -f.  Thompson Automation's TAWK
+# version 5.0c, last released in 1998 and no longer commercially available, can
+# provide the AWK script name that follows -f from the PROGFN built-in
+# variable.  It should also provide the invoking program name, E.G. TAWK, from
+# ARGV[0] but due to a bug it holds the fully qualified -f name instead.
+#
+# This example is posted here with hopes the TAWK built-in variables PROGFN
+# (PROGram File Name) and PROGLN (PROGram Line Number) be added to GAWK by its
+# developers.
