Re: Macro code

You should start with PROC COMPARE, and taket it from there...

Re: Macro code

?

"Macro" meaning what?. Can't you embed PROC's in the macro?

Otherwise, you can use SAS File I/O functions, which can call from %sysfunc. But I believe thatwill generate some more coding...

Re: Macro code

Below code should give you a start. Now it's only about wrapping a macro around the code (if you must) where you pass libname and tablenames.

data have1;
   set sashelp.class;
run;

data have2;
   set sashelp.class;
/*   label sex='Different from have1';*/
run;


%let Same_Flg=0;
proc sql noprint;
   select count(*) into Smiley Frustratedame_Flg
   from
      (
      select name, type, length, npos, varnum,label,format,informat,notnull,precision,transcode
         from dictionary.columns where libname='WORK' and memname='HAVE1'
      outer union corr
      select name, type, length, npos, varnum,label,format,informat,notnull,precision,transcode
         from dictionary.columns where libname='WORK' and memname='HAVE2'
      )
      group by name, type, length, npos, varnum,label,format,informat,notnull,precision,transcode
      having count(*) ne 2
   ;
quit;

%let Same_Flg=%eval(&Same_Flg = 0);

/* Same_Flg: 1 if no differences, 0 if differences */
%put XXXX &Same_Flg;
