9.10 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
D16
function to create variable logs.
You can assign a linear sequence of characters (letters, numbers,
special characters and spaces) up to a length of 255 characters to
a string parameter. You can also check and process the assigned
or imported values using the functions described below. As
in Q parameter programming, you can use a total of 2000 QS
parameters.

When you use the
STRING FORMULA
function, 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.
