2. © OCS Consulting Goal of this presentation To show the audience a way to develop an application with a familiarly looking user interface that is based on SAS technology on the background.

3. Agenda Introduction The user interface A simple example The SAS backend Communication A more complex example Programming practices Conclusion Questions © OCS Consulting

4. Introduction Why such applications? What do I need? The components of an application © OCS Consulting

5. Five major components User interface Call to SAS program SAS programs SAS Workspace Server Information Dataset © OCS Consulting

6. Information Dataset Regular SAS dataset in WORK Describes every (changing) element on the user interface Columns like Element Name, Element Type, Value, Enabled Y/N, Visible Y/N Examples later in the presentation © OCS Consulting

7. User Interface Developed independently from SAS Communicates with SAS Any preferred language, also web Can be replaced after completion © OCS Consulting

8. A simple example © OCS Consulting 5+5*5 30 %let calc=5+5*5; %include calculate.sas; /** CALCULATE.SAS **/ data work.calc; result = &calc.; dun; data work.ids; set work.calc; name = CalcResult; type = TextBox; value = put(result, 8.); run; /* End of Program. */ %let calc=5+5*5; %include calculate.sas; /** CALCULATE.SAS **/ data work.calc; result = &calc.; run; data work.ids; set work.calc; name = CalcResult; type = TextBox; value = put(result, 8.); run; /* End of Program. */ dataset work.ids NameTypeValue CalcResultTextBox30

9. The SAS backend SAS Workspace Server UI creates SAS code SAS code is executed by WS © OCS Consulting

10. Communication Two-way communication From UI to SAS: code and macro vars From SAS to UI: information dataset © OCS Consulting

A More Complex Example © OCS Consulting %let GrpTrials=S83-01-B12; ===== getPatients.sas ===== data work.ids; set db.patients (where = (trial = &GrpTrials)); field = GrpPatients; value = patno; visible = Y; run; /* End of Program. */ %include getPatients.sas; (where = (trial = &GrpTrials)); S83-01-B12 S83-01-B12 FieldValueVis.

13. A More Complex Example © OCS Consulting %let GrpTrials=S83-01-B12; %let GrpPatients=001002; %include DataEntry.sas; ===== DataEntry.sas ===== %createIDSforVisits(tr=&GrpTrials, pt=&GrpPatients); %createIDSforLabGroups(tr=&GrpTrials); %createIDSforLabParams(tr=&GrpTrials); === %createIDSforVisits === work.visits; set ds.visits (where); field = GrpVisits; value = visitname; visible = Y; output; field = LBVisit; value = Visit; visible = Y; output; run; ==%createIDSforLabGroups== proc sql noprint; create table work.labgrps as select distinct(labgrp) as value from ds.labdata; quit; data work.labgrps; set work.labgrps; field = LBLabGrp||_n_; visible = Y; run; ==%createIDSforLabParams==... you get my drift! data work.ids; set work.visits work.labgrps work.labprms; keep field value visible; run; /* End of Program. */

19. Conclusion Users cannot read or edit the application or SAS code Output doesnt require additional validation if programs dont change Important to define design upfront Windows-based interface makes it user friendly © OCS Consulting
