How does if/then else statement work in basic?

The IF… THEN… ELSEIF…ELSE control statement allows identifying if a certain condition is true, and executes a block of code if it is the case. The ELSE clause, while following the “IF 2<3” statement, is associated with the “IF X<2” statement, because the “IF 2<3” statement has a PRINT statement on the same line.

Why do I get an infinite loop in GW BASIC?

“Goto” tells the program to jump to the line indicated (in this case 10). Thus our program will print the 2 words, then execute line 20. Since this line tells it to go back to line 10, we get what’s termed an “infinite loop”. Usually this is the result of a programming error or bug.
