9.10 String Parameters
String processing functions
You can use the QS parameters to create variable character strings.
You can output such character strings for example through the FN
16:F-PRINT
function to create variable logs.
You can assign a linear sequence of characters (letters, numbers,
special characters and spaces) up to a length of 256 characters to a
string parameter. You can also check and process the assigned or
imported values by using the functions described below. As in Q
parameter programming, you can use a total of 2000 QS parameters
(see also ”Principle and Overview” on page 294).
The STRING FORMULA and FORMULA Q parameter functions
contain various functions for processing the string parameters.

When you use a STRING FORMULA, the result of the
arithmetic operation is always a string. When you use the
FORMULA function, the result of the arithmetic operation
is always a numeric value.
