Variable declarations
Before a variable can be referenced in a program, it must be declared. The declaration gives the variable a unique name, a type and, optionally, an initial value. See also Assignments.
A variable declaration statement can appear anywhere in a block. Variables declared in a block are in scope in that block and can be used in statements that follow the declaration.
location rect := location(1.0, 1.0, 5.0, 5.0);
integer i;
boolean c := true, d := false;
sequence <integer> s := [1, 3, 5, 7, 11, 13, 17];
string s1 := "abcdefghijklmnopqrstuvwxyz";
