┌◄────────────────────────── , ──────────────────────────┐ ── REAL ─┴─<real identifier>─┬──────────────────────────────────┬─┴────┤ └─ := ──<real constant expression>─┘
Explanation
A real declaration declares a variable of type REAL. The default initial value of a real variable is 0.
If the clause := real constant expression is specified for a real identifier, this real constant expression is used as the initial value for that real identifier.
The values of real variables are saved across a halt/load and are restored when the job restarts.
