Invoke external SAS macros in a SAS program

Autocall macro and %include are two common methods to invoke external SAS macros in a SAS program.

Method I: Autocall macro

%let path=/abc/dev/code/xyz;

option mlogic mprint symbolgen merror source source2 mrecall mautosource sasautos=(
"&path"
"!SASROOT/sasautos");

*macro call of SAS program;
%EXAMPLE;

Method II: %include

%include "/abc/dev/code/xyz/EXAMPLE.sas";

Details of related System Options used:

MERROR - issues the following warning message when the macro processor cannot match a macro reference to a compiled macro:

WARNING: Apparent invocation of macro %text not resolved.

SOURCE - specifies to write SAS source statements to the SAS log.

SOURCE2 - specifies to write to the SAS log secondary source statements from files that have been included by %INCLUDE statements.

MRECALL - searches the autocall libraries for an undefined macro name each time an attempt is made to invoke the macro. It is inefficient to search the autocall libraries repeatedly for an undefined macro. Generally, this option is used while developing or debugging programs that call autocall macros.

!SASROOT:

The !SASROOT directory contains the files required to use SAS. This directory includes invocation points, configuration files, sample programs, catalogs, data sets, and executable files.
