===Variables===
Variables are meant to pass values between activities and are therefore very important for the logic of a workflow. So if you want to i.e. pass a string from activity A to activity B, you need to
* create a variableof type ''String''
* assign it to an out string parameter of activity A
* assign it to the in string parameter of activity B
{{Attention|Unlike function or method names, variable names are case-sensitive}}
