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 230).
The STRING FORMULA and FORMULA Q-parameter functions
contain various functions for processing the string parameters.
STRING FORMULA functions Soft key Page
Assign string parameters Page 280
Chain-link string parameters Page 280
Convert a numerical value to a string
parameter Page 282
Copy a substring from a string parameter Page 283
FORMULA string functions Soft key Page
Convert a string parameter to a numerical
value Page 284
Check a string parameter Page 285
Find the length of a string parameter Page 286
Compare alphabetic priority Page 287
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.
