More than one Statement per Branch

Here is the program again with some added statements:

PRINT "Enter a Number"
INPUT NUMBER
'
IF NUMBER >= 0 THEN
  PRINT "The number is zero or positive"    ' true branch
  PRINT "Positive numbers are > 0"          ' true branch
ELSE
  PRINT "The number is negative"    ' false branch
  PRINT "Negative numbers are < 0"  ' false branch
END IF
'
PRINT "Bye"     ' this statement is always done
END

The statements in the true branch are executed when the question in the IF statement is TRUE. There can be as many statements as you want in the true branch. The true branch consists of the statements between the IF statement and the ELSE statement.

Of course, the statements in the false branch are executed when the question in the IF statement is FALSE. There can be as many statements as you want in the false branch. The false branch consists of the statements between the ELSE statement and the END IF statement.
