In programming, what does a 'CALL' command typically do?

The 'CALL' command is a fundamental feature in many programming languages, including those used for robot programming. Its primary function is to initiate or invoke a subprogram, which is a set of instructions designed to perform a specific task within the main program.

Using the 'CALL' command allows for modular programming, where complex processes can be broken down into smaller, manageable pieces of code. This not only enhances readability but also promotes code reusability, as the same subprogram can be called multiple times from different locations within the main program, reducing redundancy.

In the context of robot programming, calling a subprogram can enable the robot to execute a sequence of operations without rewriting the entire procedure each time it is needed. This modular approach is instrumental in maintaining and updating code efficiently, which is crucial for effective robot control and automation.
