In the case of an If-Then command in programming, if the conditions specified by the If part are met, the program will execute all commands that are placed between the beginning of the Then section and its corresponding end statement.
The exact notation for the end of this block of code may vary depending on the programming language being used (e.g., 'endif', 'end', or just a closing curly brace }). It's important to follow the syntax rules of the language for the code to run correctly.
