text procedure SUB(i,n); integer i,n;   Returns a reference to a part of the text of 
                                        length n, starting at the i:th character. T.SUB(5.2) will return a 
                                        reference to the sub-string "EF" above.
text procedure STRIP; Returns a reference to a sub-string where all trailing spaces 
                                        and tabs have been skipped.
text procedure MAIN; This is the inverse of SUB and STRIP - returns a reference to                
                                        the full string. T.SUB(5,2).MAIN==T
integer procedure START; Returns the index within the MAIN-string of where the    
                                        SUB-string starts: T.SUB(5,2).START=5.
