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

Further Information:
