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 D16
function to create variable logs.
You can assign a linear sequence of characters (letters, numbers,
special characters and spaces) up to a length of 255 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 "Principle and overview of functions", page 290).
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.
