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
FN16:F-PRINT

function to create variable logs.

You can assign a linear sequence of characters (letters, numbers,
special characters and spaces) to a string parameter. You can also
check and process the assigned or imported values by using the
functions described below.

The STRING FORMULA and FORMULA Q-parameter functions
contain various functions for processing the string parameters.

FORMULA function, the result of the arithmetic operation
is always a numeric value.
