In "Expressions", you can select from a drop-down menu, expressions to use in a general formula, and if you select variables, this will output the values stored in them.
(Example) If the value stored in variable "name" is "Tanaka"
▼Select the variable "name"
▼The value stored in the variable is output
In "Expressions", fixed texts shall be surrounded with symbols such as " " or >> << but this is not necessary for variables.
※For details about methods to describe expressions that include fixed texts, please refer to: "How to formulate statements when using strings of characters, variables or the newline character \n in expressions in DS?".
Please be careful when using symbols that express constants such as " " or >> << on variables because your variable name will be interpreted as a fixed text.
For more information about expressions you can select other than variables, please refer to the link below.
