10.11 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 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.
"Principle and overview of functions",
The
STRING FORMULA
and
FORMULA
Q parameter functions
contain various functions for processing the string 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.
