When writing a script the function Set Variable is available. My question is. After you Set the Variable how do you change it in the script. For example:

What if I Set Variable $Examp to 25. Then later in the script I want to add 15 to the variable.

Do I just do another Set Variable with the same name?

Set Variable [ $Examp ; Value: 25 ]

... do several script steps

Set Variable [ $Examp ; Value: $Examp + 15 ]

...then you can set a field with the returned value of 40 as: Set Field [ field ; $Examp ]

When in doubt, create a field and try setting it with various configurations. Math is great for testing because the logic is clear. And you have Data Viewer (FMA); you can use it to evaluate or monitor your variables. It's very cool!
