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 "Principle and overview of functions", page 240).
The STRING FORMULA and FORMULA Q-parameter functions
contain various functions for processing the string parameters.
STRING FORMULA functions
Assigning string parameters
Chain-linking string parameters
Converting a numerical value to a
string parameter
Copy a substring from a string
parameter
FORMULA string functions
Converting a string parameter to a
numerical value
Checking a string parameter
Finding the length of a string
parameter
Compare alphabetic priority
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.
