Creating variables to use with objects

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.
