Here is an awk approach:
Code:
awk '
        {
                for ( i = 1; i <= NF; i++ )
                {
                        if ( $i == "LLL" && $( i + 1 ) == "SSS" )
                        {
                                F = 1
                                i += 2
                        }
                        if ( $i == "AAA" && $( i + 1 ) == "RRR" )
                        {
                                F = 0
                        }
                        if ( F )
                                s = s ? s OFS $i : $i
                }
                if ( s )
                {
                        print s
                        s = ""
                }
        }

Tcl_StringMatch(3)					      Tcl Library Procedures						Tcl_StringMatch(3)

__________________________________________________________________________________________________________________________________________________

NAME
Tcl_StringMatch, Tcl_StringCaseMatch - test whether a string matches a pattern SYNOPSIS
#include <tcl.h> int Tcl_StringMatch(str, pattern) int Tcl_StringCaseMatch(str, pattern, flags) ARGUMENTS
const char *str (in) String to test. const char *pattern (in) Pattern to match against string. May contain special characters from the set *?[]. int flags (in) OR-ed combination of match flags, currently only TCL_MATCH_NOCASE. 0 specifies a case-sensitive search. _________________________________________________________________ DESCRIPTION
This utility procedure determines whether a string matches a given pattern. If it does, then Tcl_StringMatch returns 1. Otherwise Tcl_StringMatch returns 0. The algorithm used for matching is the same algorithm used in the string match Tcl command and is similar to the algorithm used by the C-shell for file name matching; see the Tcl manual entry for details. In Tcl_StringCaseMatch, the algorithm is the same, but you have the option to make the matching case-insensitive. If you choose this (by passing TCL_MATCH_NOCASE), then the string and pattern are essentially matched in the lower case. KEYWORDS
match, pattern, string Tcl 8.5 Tcl_StringMatch(3)
