The IF...THEN...ELSEIF...ELSE control statement allows identifing if a certain condition is true, and executes a block of code if it is the case.
IF number<0 THEN PRINT "Number is negative" ELSEIF number>0 THEN PRINT "Number is positive" ELSE PRINT "Number is zero" END IF
In some implementations of BASIC (put permitted by most versions), the IF statement may need to be contained in one line. However, ELSEIF may not be available in this case, and there is no need for an explicit END IF:
IF number<0 THEN PRINT "Number is negative" ELSE PRINT "Number is non-negative"
