Creating variables in WayScript is done using standard Python syntax. You can create as many variables as you like using a single Create Variable module by adding a new field to create each additional variable.
You can also use the Create Variable module to edit the value of a variable. To do this, drag the variable pill into the Create Variable module and assign the new value to the pill.
For example, suppose you created the variable "my_struct" previously in your program, but you want to change "my_struct.count" from 123 to 456.
Simply drag the "my_struct.count" pill into a new Create Variable step and assign it the new value.
