About Variables

When robots perform actual tasks, temporary necessary information (e.g., ID/PW, folder names) often needs to be remembered. This can be efficiently managed using the commonly utilized feature known as variables.

1. What is a Variable?

A variable is a "box for storing values." From the perspective of developing a robot, it serves as a place where information temporarily remembered by the robot is stored.

Variables are used for defining, changing, and referencing that information.

For example, if you want a robot to log into a business system, you first define two variables: "ID" and "PASSWORD." Then, retrieve the ID and password from a specific Excel file and store them in the defined variables. Finally, the robot logs into the system by referencing the information stored in the "ID" and "PASSWORD" variables.

2. About Data Types

Various types of information (such as strings and numbers) can be stored in variables. These types are commonly referred to as "data types." The table below introduces data types commonly used by robots.

Data Type	Description	Example
String	Used for handling text	Example: "A" (Enclosed in quotes)
Int32	Used for handling integers (without decimal points)	Example: 1 (Mainly for calculations)
Double	Used for handling numbers (including decimals)	Example: 0.1 (Mainly for decimal calculations)
Boolean	Used for handling boolean values	Example: True or False (Mainly used in conditional branches. Default is False.)
Array	Used for handling arrays	Example: { "A", "B" } (Stores single or multiple values within braces. The example is a String[].)
DataTable	Used for handling table-like data (rows and columns)	Structured format with rows and columns. (Mainly used for Excel and CSV operations.)
DateTime	Used for handling dates	Example: 2020/04/01 (Date display format can be specified. Initial value is 0001/00/00 0:00:00.)

Understanding and utilizing variables effectively can greatly enhance the robot's ability to perform complex tasks by remembering and manipulating necessary information dynamically.
