4. Declarations, declarers and indicators {Declarations serve
· to announce new indicators, e.g., identifiers,
· to define their modes or priorities, and
· to ascribe values to those indicators and to initialize variables.}
4.1.1. Syntax A) COMMON :: mode ; priority ; MODINE identity ; reference to MODINE variable ; MODINE operation ; PARAMETER ; MODE FIELDS. {MODINE :: MODE ; routine.}
a) NEST declaration of DECS{a,32b } : NEST COMMON declaration of DECS{42a ,43a,44a,e,45a,-}; where (DECS) is (DECS1 DECS2), NEST COMMON declaration of DECS1{42a ,43a,44a,e,45a,-}, and also{94f } token, NEST declaration of DECS2{a}.
b) NEST COMMON joined definition of PROPS PROP {b,42a ,43a,44a,e,45a,46e,541e} : NEST COMMON joined definition of PROPS{b,c}, and also{94f } token, NEST COMMON joined definition of PROP{c}.
c) NEST COMMON joined definition of PROP {b,42a ,43a,44a,e,45a,46e,541e} : NEST COMMON definition of PROP{42b ,43b,44c,f,45c,46f,541f,-}.
d) *definition of PROP : NEST COMMON definition of PROP {42b ,43b,44c,f,45c,46f,541f} ; NEST label definition of PROP{32c } . {Examples:

4.1.2. Semantics
The elaboration of a declaration consists of the collateral elaboration
of its COMMON-declaration and of its declaration, if any.
{Thus, all the COMMON-declarations separated by and-also-tokens
are elaborated collaterally.}
