@@ -4907,6 +4907,25 @@ function names added by @command{gawk} after the code was written.
 Standard @command{awk} built-in functions, such as @code{sin()} or
 @code{substr()} are @emph{not} shadowed in this way.
 
+The @code{PROCINFO["argv"]} array contains all of the command-line arguments
+(after glob expansion and redirection processing on platforms where that must
+be done manually by the program) with subscripts ranging from 0 through
+@code{argc} @minus{} 1.  For example, @code{PROCINFO["argv"][0]} will contain
+the name by which @command{gawk} was invoked.  Here is an example of how this
+feature may be used:
+
+@example
+awk '
+BEGIN @{
+        for (i = 0; i < length(PROCINFO["argv"]); i++)
+                print i, PROCINFO["argv"][i]
+@}'
+@end example
+
+Please note that this differs from the standard @code{ARGV} array which does
+not include command-line arguments that have already been processed by
+@command{gawk} (@pxref{ARGC and ARGV}).
