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 202).
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 246
Chain-link string parameters Page 246
Convert a numerical value to a string
parameter Page 248
Copy a substring from a string parameter Page 249
FORMULA string functions Soft key Page
Convert a string parameter to a numerical
value Page 250
Check a string parameter Page 251
Find the length of a string parameter Page 252
Compare alphabetic priority Page 253
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.
