MAPABLOPEREXPR(3)		 ABL FUNCTIONS		     MAPABLOPEREXPR(3)

NAME
       mapabloperexpr -	applies	a function to all operands.

SYNOPSIS
       #include	"abl101.h"
       chain_list *mapabloperexpr( Function, Oper, Expr	)
	 chain_list * (*Function)();
	 long	    Oper;
	 chain_list *Expr;

PARAMETERS
       Function		   Function name to apply to all operands.

       Oper		   Operator number.

       Expr		   Expression to scan.

DESCRIPTION
       mapabloperexpr  applies	Function to all	operands of Expr.  mapabloper-
       expr creates a head of an operator expression having Oper  as  operator
       and  adds  the  arguments calculated by applying	Function to each argu-
       ments of	Expr.  Function	must return an	expression  and	 must  have  a
       unique expression as argument.

RETURN VALUE
       mapabloperexpr returns a	new expression by applying Function to all the
       arguments of the	operator expression Expr.

EXAMPLE
       #include	"abl101.h"
	  chain_list *MapFunction( MapExpr )
	     chain_list	*MapExpr;
	  {
	    return( createablnotexpr( dupablexpr( MapExpr ) ) );
	  }
	  chain_list *Expr;
	  chain_list *Expr1;
	  Expr = createablbinexpr( ABL_NOR,
				   createablatom( "a" ),
				   createablatom( "b" )	);
	  Expr1	= mapabloperexpr( MapFunction, ABL_AND,	Expr );
	  /* displays ((not a) and (not	b))  */
	  viewablexpr( Expr1, ABL_VIEW_VHDL );
