Expressions

Each of the three broad type classes has its own set of intrinsic (in-built) operators, for example, +, // and .AND.,

The following are valid expressions,

• NumBabiesBorn+1 -- numeric valued
• "Ward "//Ward -- character valued
• TimeSinceLastBirth .GT. MaxTimeTwixtBirths -- logical valued

Expressions can be used in many contexts and can be of any intrinsic type.
