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.
STRING FORMULA functions
Assigning string parameters
Chain-linking string parameters
Converting a numerical value to a string
parameter
Copying a substring from a string
parameter
Copying system data to 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
Comparing 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.
