Fix

Type Function: STRING

Input STR	STRING (String input)
L	INT (fixed-length od output string)
C	BYTE (padding character when padding)
M	INT (mode for padding)
Output	STRING (string of fixed length N)
	FIX creates a string of fixed length N. The string STR at the input is truncated to the length N respective filled with the fill character C. If the string STR is shorter than the length L to be created, will the string be filled depending on M, with the fill character C. If M = 0, the padding at the end of the string is appended, if M = 1, the padding is attached the beginning and when M = 2, the string is centered between fill character. If the number of the necessary padding is odd and if M = 2, the fill at the end has a fill character more than at the beginning. The FIX function evaluates the Global Setup string_length constant and limits the maximum length L of the string to string_length.
