9.11 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 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 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.
