9.9 String Parameters

String processing functions

You can use the QS parameters to create variable character strings.

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 274).

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.
