NAME

6       mapabloperexpr - applies a function to all operands.
7

SYNOPSIS

9       #include "abl101.h"
10       chain_list ∗mapabloperexpr( Function, Oper, Expr )
11         chain_list ∗ (∗Function)();
12         long       Oper;
13         chain_list ∗Expr;
14

PARAMETERS

16       Function            Function name to apply to all operands.
17
18       Oper                Operator number.
19
20       Expr                Expression to scan.
21

DESCRIPTION

23       mapabloperexpr   applies  Function  to  all  operands  of  Expr.
24       mapabloperexpr creates a head of an operator  expression  having
25       Oper  as  operator and adds the arguments calculated by applying
26       Function to each arguments of Expr.   Function  must  return  an
27       expression and must have a unique expression as argument.
28

RETURN VALUE

30       mapabloperexpr  returns a new expression by applying Function to
31       all the arguments of the operator expression Expr.
32

EXAMPLE

34       #include "abl101.h"
35          chain_list ∗MapFunction( MapExpr )
36             chain_list ∗MapExpr;
37          {
38            return( createablnotexpr( dupablexpr( MapExpr ) ) );
39          }
40          chain_list ∗Expr;
41          chain_list ∗Expr1;
42          Expr = createablbinexpr( ABL_NOR,
43                                   createablatom( "a" ),
44                                   createablatom( "b" ) );
45          Expr1 = mapabloperexpr( MapFunction, ABL_AND, Expr );
46          /* displays ((not a) and (not b))  */
47          viewablexpr( Expr1, ABL_VIEW_VHDL );
