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 272).

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

Formula string functions

Converting a string parameter to a

numerical value

Checking a string parameter

Finding the length of a string

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.
