NAME

       substdupablexpr - substitutes a given atom by an expression.

SYNOPSYS

       #include "abl101.h"
       chain_list ∗substdupablexpr( Expr1, Name, Expr2 )
         chain_list ∗Expr1;
         char       ∗Name;
         chain_list ∗Expr2;

PARAMETERS

       Expr1               First expression.

       Name                Atom name.

       Expr                Second expression.

DESCRIPTION

       substdupablexpr duplicates and substitutes Atom in Expr1 by Expr2.

RETURN VALUE

       substdupablexpr returns the duplicated and modified expression.
