15.2.25 FC 24 - LT_STRNG - Compare STRING for smaller
The function FC 24 compares the contents of two variables in the format STRING to
determine if one is smaller to the other and outputs the result of the comparison as a
return value. The return value has the signal state "1" if the string at parameter S1 is
smaller than the string at parameter S2. The characters are compared by their ASCII
code (e.g. 'A' smaller than 'a'), starting from the left. The first character to be different
decides the result of the comparison. If the left part of the longer character string and the
shorter character string are the same, the shorter string is smaller. The function does not
report any errors.

15.2.26 FC 25 - MAX - Select maximum
The function FC 25 selects the largest of three numerical variable values.
n Variables of the data types INT, DINT, and REAL are permitted as input values.
n All variables with parameters assigned must be of the same data type.
n The variable type is recognized by the ANY pointer.
n The output value remains unchanged and the BR bit is set to "0" if:
– a variable with parameters assigned has an invalid data type.
– all variables with parameters assigned do not have the same data type.
– a REAL variable does not represent a valid floating-point number.

IN1 INPUT ANY I, Q, M, D, L 1. Input value
IN2 INPUT ANY I, Q, M, D, L 2. Input value
IN3 INPUT ANY I, Q, M, D, L 3. Input value
