Pascal User Manual and Report says:
Procecure (function) identifiers may be used be-
fore the procedure (funtion) declaration if
there is a forward declaration. Forward decla-
rations are necessary to allow mutually recur-
sive procedures and functions that are not nest-
ed. The form is as follows:
procedure Q(X:T); Forward;
procedure P(Y:T);
begin
Q(A)
end;
procedure Q;
{ parameters and result types are not repeated }
begin
P(B)
end;
But are "mutually recursive procedures and func-
tions" necessary?
