The simplest objects of data are single numbers of floating, fixed-point or integer types. Identifiers may refer to such objects if suitably declared, e.g.
INTEGER i, j, k; FIXED(13,5) x, y;
and the declarations may optionally include assignment of initial values. This is known as presetting and is described in Section 4.6. The syntax for a number declaration is
Numberdec ::=
Numbertype
Idlist
Presetlist
Idlist ::=
Id
Id ,
