appear on the left side of an assignment. Examples of lvalues are
variables, parameters, array element references such as
a[i],
struct element references such as s->name or s.name, and
pointer dereferences such as
*ptr. Expressions that are not lvalues
are called rvalues.

the possible command choices.

array, or a reference parameter of type integer, long, single-precision,
or double-precision.
