Is there any method to isolate or separate each module to avoid potential interference issues due to naming of libraries, variables, global macro variables, or macro names?</P> Fri, 17 Jan 2020 22:19:28 GMT https://communities.sas.com/t5/SAS-Programming/Modularizing-or-Isolating-SAS-Programs/m-p/618214#M181320 Junyong 2020-01-17T22:19:28Z https://communities.sas.com/t5/SAS-Programming/Modularizing-or-Isolating-SAS-Programs/m-p/618219#M181324 <P>What do you mean by "isolate" a program?
