Decision making basically has to do with the if-else statement. The if-else statement executes an action based on the decision made e.g if I have more than 10 bucks, I'll get a software CD else I'll buy a sandwich. That's a simple demonstration. Let's glance through the syntax:

n = 9

if ( n < 1 )
	display "  yea n is "   n   " and is less than 10"   crlf
elif ( n == 1 )
	display "  n is 1 "   crlf 
elif ( n > 10 )
	display "  well you inputed "   n   " which is greater than 10"   crlf
	n = 34
end

In the above example, the first display statement is executed if n is less than 1 elif n == 1, the second display statement is executed else, the last display statement is executed.

The elif word, means else if, It is grabbed from Ruby.

The if-else statement, also has it's sub statements enclosed in brackets only if the argyments are not enclosed in parenthesis (). Example:

if n < 30 {
	display "  it also less than 30"
elif n > 30
	display "  greater than 30"
else 
	display "flooped"
}

Note that it is compulsory to end the if-else statements with the end keyword to avoid errors.
