# Purpose: non-printing characters # This file contains control-K, control-L and control-M "white-space" # characters in the loop, which should parse without error. But there # are other illegal non-printing characters. data_model _d1 char _d2 'model file' _d3 "with various types of field" _d4 # Control-G in the next text field ; all conforming to valid STAR syntax  rules ; loop_ _d5 _d6 _d7 _d8 A B C D E F G H # Comment I J K L # File ends with a control-Z (sometimes appended by DOS programs) - this # should be flagged both as an illegal character and as a surplus member # of the loop above!
