Using variables in Astrato
You can use variables in Action flows and add interactions by changing a layer's visibility.
Variables can act as containers to help you make changes across your data, where a single change to the variable is enough; you don't need to change an item or data object.
Types of variables
In Astrato, you can store boolean, number, and string variables.
Boolean variables have only two possible values: true or false. They're most commonly used with control statements to determine the flow.
Number variables are used to store numeric information. Use them to perform equations or comparisons.
String variables hold a sequence of characters, such as letters, words, phrases, or symbols. They're used to store text, for example, a sentence or paragraph or even a single character.
String sub-types - the default type is plain text, but you can also enter a SQL query.
