Making SAS/EIS Applications Run Smoothly

You can perform several tasks to ensure that your SAS/EIS applications work properly.

If you create SAS files other than the defaults for SAS/EIS software, you must assign exactly the same librefs for the SAS libraries that contain those files before you next invoke SAS/EIS.

In addition, before you execute SAS/EIS applications, you must assign exactly the same librefs and filerefs that you assigned when you defined them. This includes librefs for libraries that contain repositories, catalogs with FRAME entries, application databases, and so on. You can automate these libref and fileref assignments with command files, scripts, SAS macros, or other similar files to ensure correct processing.
You can also put all of the other tasks specific to invoking your customized SAS/EIS sessions into command files, scripts, SAS macros, or other similar files to automate your use of SAS/EIS and to ensure correct processing.
You can develop initialization methods that assign librefs, create SAS tables, or perform other tasks before executing the SAS/EIS application.
You can define a SAS/EIS menu application that invokes other SAS/EIS applications, and you can use the RUNEIS command to execute a main menu or a Welcome application.
You can define a SAS/EIS Script application that executes a series of other SAS/EIS applications sequentially. Script applications can execute other SAS/EIS applications that assign librefs, filerefs, and so on, and finally a main menu or a Welcome application. You can then execute the Script application with the RUNEIS command.
