String parameters

String processing functions

You can use the

QS parameters to create variable character strings.

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 248).
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.
