8.10 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 210).
The STRING FORMULA and FORMULA Q parameter functions
contain various functions for processing the string parameters.
STRING FORMULA functions Soft key Page
Assigning string parameters Page 254
Chain-linking string parameters Page 254
Converting a numerical value to a string
parameter Page 256
Copying a substring from a string
parameter Page 257
FORMULA string functions Soft key Page
Convert a string parameter to a numerical
value Page 258
Checking a string parameter Page 259
Finding the length of a string parameter Page 260
Comparing alphabetic priority Page 261
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.
