PARAMETER attribute
Standard: F77 F90 F95 F2003
  Example Program
<Syntax>
type, PARAMETER [ , attr ] :: decl-list

PARAMETER ( name=expr [ , name=expr ]...

In a type declaration statement with the PARAMETER keyword, each decl in the decl-list must supply a value.

Each name must be implicitly typed or have its type specified in a prior type declaration. The type of each expr in a PARAMETER statement must be assignment compatible with its corresponding name.
<Semantics>
The PARAMETER attribute specifies that an entity is a named constant. If the type, kind or character length of the expr differs from that of the name, the value is converted using the same rules as intrinsic assignment.
