4.2. Simple References

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 ,  Idlist
