Conditionals - in COBOL and Java

declare age as binary-long = 10
declare greeting as string
*>greeting = age < 20 ? has no directly equivalent syntax in COBOL

if age < 20
   move "What's up?" to greeting
else
   move "Hello" to greeting
end-if

declare x as binary-long = 200
declare y as binary-long = 3
if x not = 100 and y < 5
   multiply 5 by x
   multiply 2 by y
end-if



*> evaluate is preferred in COBOL rather than if/else if/else
evaluate x
when > 5
   multiply y by x
when 5
   add y to x
when < 10
   subtract y from x
when other
   divide y into x
end-evaluate





declare color as string = "blue"
declare r b g other-color as binary-long
evaluate color   *> can be any type
when "pink"
when "red"
   add 1 to r
when "blue"
   add 1 to b
when "green"
   add 1 to g
when other
   add 1 to other-color
end-evaluate
