Problem to be solved:
1. save macros in files, save to somewhere in disk
2. load the macros in Autocall Library

Method:
1. define macros, save filename = macro name, in lower case
2. use filename macroName 'fileLocation.sas'
3. add to autocall library:
OPTIONS MAUTOSOURCE SASAUTOS=(freqmeans sumdollar SASAUTOS);

FILENAME sumdollar 'E:\ChenyxFiles\2014.Study.TrainingCertificate\SAS.Victoria\SAS.DS2\SASUniversityEdition\myfolders\Macro.OOP\Analysis\prjName\macro\sumdollar.sas';


OPTIONS MAUTOSOURCE SASAUTOS=(freqmeans sumdollar SASAUTOS);
