Macro not resolved even adding in the SASAUTOS

RahulG — Wed, 03 Aug 2016 06:32:24 GMT

I am running on SAS 9.4 environment.

In my macro folder "c:\macro", I have two files a.sas and b.sas. a.sas contains %a definition and similary b.sas contain %b definition

%a;

filename mac_ref "c:\macro";
options APPEND = SASAUTOS=(,mac_ref);

%b;

%a;

call of %b is successfull and call %a throws error "Apparent symbol not resolved".

Problem that I am facing is If I call any macro before Options append then it do not resolve at all in the session, even after reference appended in SASAUTOS.

What you are seeing is standard SAS behaviour. When you first call %A it will not be found as SASAUTOS follows. SAS defines a dummy macro called A since it cant find the real A. This then blocks you from finding the real A after your SASAUTOS statement.

A good practice is to put your SASAUTOS statement into your AUTOEXEC.SAS program so it will be run each time you start SAS. That way even a macro call as your first program statement will always work.

It should be LIBNAME not FILENAME, if I was right.

It is filename.

Set the system option mrecall. That tells SAS to search the autocall library every time it sees a macro reference, even if it has previously searched and not found it. (The docs says this is inefficient and should only be used in development.)

That is a SAS program file , Not compiled macro of SAS .
You can't use it in this way. Should be :

%include 'c:\temp\a.sas';

%include 'c:\temp\b.sas';
