SYNOPSYS

       #include "abl101.h"
	void *getablexprsupport( Expr, Mode )
	 chain_list *Expr;
	 int	     Mode;

PARAMETERS

       Expr		   Expression.

       Mode		   The returned support's mode.

DESCRIPTION

       getablexprsupport gives the support of Expr. if Mode is ABL_SUPPORT_CHAIN the support is returned using	chain_list  else  it  is  returned
       using ptype_list. The support must be freed using the freechain or freeptype functions.

RETURN VALUE

       getablexprsupport returns a pointer to a chain_list or a ptype_list.

EXAMPLE

       #include "abl101.h"
	 chain_list *Expr;
	 ptype_list *Support;
	 ptype_list *ScanSupport;
	 Expr = createablbinexpr( ABL_AND,
				  createablatom( "a" ),
				  createablatom( "b" ) );
	 Support = getablexprsupport( Expr, ABL_SUPPORT_PTYPE );
	 /* displays a b */
	 for ( ScanSupport  = Support;
	       ScanSupport != (ptype_list *)0;
	       ScanSupport  = ScanSupport->NEXT )
	 {
	   printf( "%s ", (char *)ScanSupport->DATA );
	 }
	 freeptype( Support );
