Token label declaration

Hello,

In this custom code, if I do not have the ptointermedio label defined for the token at any point in the Process Flow, why does it not give an error?

At what point is the ptointermedio label defined so that it does not cause errors?

This is the process Flow on which the process is based:

Thank you.

Software Version:

FlexSim 24.1.1

Assigning a value to a label will create the label if it is not yet present. Only trying to read a non-existant label will cause an error.

Writing

token.labelName = 1;

is the same as writing

token.labels.assert("labelName").value = 1;

in that regard.

Note that this is only true for labels, not other subnodes or attributes.

Also note that these are not the same as

token.labels.assert("labelname",1);

which only sets the label to 1 if the label did not already exist.

I found this structure in the manual that somewhat contradicts what you told me in your last answer.

If there is any difference with your construction, could you explain it to me, please.

Thank you!!

The example in the manual combines both expressions. It creates the label if it does not exist yet ("labels.assert("MyLabel", 1)") and then increments the current value of the label by 10. (".value += 10"). If the label did not exist previously (or already had a value of 11) its value would now be 11. If the label did exist with, for example, a value of 7, it would now have a value of 17.

Only using

current.labels.assert("MyLabel").value += 10

would likely result in the value 10, since the label would not get a fixed initial value and most likely get initialized with a value of 0.
