These files consist of ASCII records of fixed lengths (126 bytes). Each record is separated by two characters like as in DOS, which are one "control M" (carriage return, ASCII code 0Dh) and one "control J" (line feed, ASCII code 0Ah).

For a missing value, the character '-'(ASCII code 2Dh) is put in place of the measured value. The column of the parameter that was not observed is filled with blanks.
