10.11 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 255 characters to
a string parameter. You can also check and process the assigned
or imported values using the functions described below. As
in Q parameter programming, you can use a total of 2000 QS
parameters.

arithmetic operation is always a numeric value.
