Hi Angeman
What does an action in rules "Set variable" do?

[Angeman]

It saves the value of something into a "variable" that you can then use in the following actions of your rule.

Hi Angeman
I’m not understanding completely how does it work
Could you show please?

I’m using rules now: I want certain transactions to have “fixed” written in Splits comment field. Is it possible to use “set variable” foe this?

[Angeman]

You can't create a rule to modify the comment of a split currently sorry.

Hi Cyril,
so what does set variable do?
I’m not understanding completely how does it work
Could you show an example please?

[Angeman]

It's just a temporary buffer, for example with a transaction named "Groceries" :

• Set variable "x" to the contents of Name
  => x = "Groceries"
• Set name to "Test"
  => name of the transaction is now "Test"
• Set comment to the variable "x"
  => comment of the transaction is now "Groceries"
