# this program shows basic line control
#  pmb 10/1/02

# lines are usually executed one after the other
print "this line comes frst"
print "then this line"

# soometimes control jumps around, if desired
x=5
y=6
# if statement does exactly like it looks
if ( x<y ):
    # do these lines if x is less than y
    print "x is less than y"
    print x,y
else:
    # otherwise, do these
    print "x is not less than y"
    print x,y

# a while loop gets executed until the condition is no longer true
i = 4
while ( i < 10 ):
    # do this until i is no longer less than 10
    print "i is less than 10 ", i
    i=i+1

print "i is no longer less than 10, it is ", i
