@@ -8077,6 +8077,19 @@ the 'awk' program in the 'ARGV' array (*note ARGC and ARGV::).  'awk'
 processes the values of command-line assignments for escape sequences
 (*note Escape Sequences::).  (d.c.)
 
+   Normally, variables assigned on the command line (with or without the
+'-v' option) are treated as strings.  When such variables are used as
+numbers, 'awk''s normal automatic conversion of strings to numbers takes
+place, and everything "just works."
+
+   However, 'gawk' supports variables whose types are "regexp".  You can
+assign variables of this type using the following syntax:
+
+     gawk -v 're1=foo|bar/' '...' /path/to/file1 're2=baz|quux/' /path/to/file2
+
+Strongly typed regexps are an advanced feature (*note Strong Regexp
+Constants::).  We mention them here only for completeness.
