Oh, that's a new one on me.

It looks like an internationalization feature, awk's equivalent of digraphs and trigraphs, multi-byte sequences which implement "extended" non-ASCII characters while still writing the program in pure ASCII. They're predefined, so [.STRING.] is meaningless, and there's a big list somewhere of what ASCII sequences actually translate to what Russian characters somewhere.

Of course, the list will be in Russian, so us ASCII-worlders probably don't know the right words to find it. It will also probably depend on being in the right extended-ascii set where they have any meaning and using some Russian subset of awk. This feature is often not implemented unless it's really needed.

So to us, not that useful. To someone's special Russian awk in Russia, it might be indispensable.

IGAWK(1)							 Utility Commands							  IGAWK(1)

NAME

       igawk - gawk with include files

SYNOPSIS

       igawk [ all gawk options ] -f program-file [ -- ] file ...
       igawk [ all gawk options ] [ -- ] program-text file ...

DESCRIPTION

       Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).

       AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like

	      @include getopt.awk

       in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.

OPTIONS

       See gawk(1) for a full description of the AWK language and the options that gawk supports.

EXAMPLES

       cat << EOF > test.awk
       @include getopt.awk

       BEGIN {
	    while (getopt(ARGC, ARGV, "am:q") != -1)
		 ...
       }
       EOF

       igawk -f test.awk
