Do you want to change the name or the value?

here I duplicate name character and value of label on process finish. Label is first in labels view.

item.attrs.labels.subnodes[1].name+=item.attrs.labels.subnodes[1].name; //enhance name
item.attrs.labels.subnodes[1].value+=item.attrs.labels.subnodes[1].value;// duplicate value

my concrete problem is not to duplicate the name but to change it completely (the simplification of my problem is the following:
 if the value ( type string) of the label at the input (coming from the source) is " spring "then 
      on process finish I want to have a value label" hardened spring ". 
and if the label at the input is "bolt" then
      on process finish I want at the output a value label "hardened bolt"

note: I am still a beginner in the use of flexsim therefore I can confuse between the concepts

You are looking for a way to manipulate a string as label value. Then you should take a look into the methods and operators to work with the string class. Working with labels is part of another class: labelProperties and labels.

If you look closer into the second suggested code line, I concatenate a string value with the same string again. In fact it uses the “+” operator. It is up to you, how you change a string value of a label. Your example shows an operation, where you add at start of a given string another string

item.myLabel = “hardened “+item.myLabel;

If you are confused, what this is all about, then I recommend you do some more tutorials, because labels are one of the most important structures inside of FlexSim.
