The “IF THEN ENDIF” construct is a fundamental decision-making tool in programming, particularly in languages like BASIC. It allows for conditional execution of code blocks based on the evaluation of a condition. Here’s an example in Python:

x = 10
if x > 5:
print(“x is greater than 5”)
endif

In this example, if the condition “x > 5” evaluates to true, the statement “x is greater than 5” is printed. Otherwise, the code block following the “IF” statement is skipped. The “ENDIF” marks the end of the conditional block. This simple yet powerful construct enables programmers to incorporate logic into their programs, directing the flow of execution based on specified conditions.
