1 Efficient Way to Learn SAS with Virtually No Cost Mirjana StojanovicStatistical ProgrammerChapel Hill, NCI will talk about myself, and how I got this idea to write such paper. In this paper I have about 15 sites, but depend of time how many of them I will present at SESUG 2003.
2 Learning from WEB sites M Stojanovic:M Stojanovic:M Stojanovic:Learning from WEB sitesFind out WEB sites which is the most suitable for your needsFollow instructions or copy and paste into SAS learning edition (optional)Check back frequently and check links which you will use the most of the time1. This is my way how I want to share Information

37 WHERE vs IFThe WHERE statement works before observation are brought into the data step(that is the PROGRAM DATA VECTOR) .The IF statement works on observation that are already in the data step.The WHERE statement is not executable, but the IF statement isThe WHERE statement operates only on observations in SAS data sets, whereas the IF statement can operate either on observations from existing SAS data sets or on observations created with an input statement.If a BY statement does not accompany a SET or MERGE statement, the WHERE and IF statements usually produce the same resultIn almost all cases a WHERE statement is more efficient than an IF statement(observations do not have to be moved into the PDV)The WHERE statement, but not the IF statement can be used in SAS PROCS .

91 SAS: the SAS Users' Group List (SUG-L) What is SUG-L?SUG-L is a listserv-based mailing list for SAS users throughout the Research Triangle area.The list provides a way for users in the area to exchange information about SAS problems and questions.Meetings of The Research Triangle SAS Users Group (RTSUG) are announced on this list.
92 SAS Newsgroup comp.soft-sys.sas This newsgroup and SAS-L are joined(mirrored) so that the messages sent to one will also be sent to the other.Deja.com Power Search provides an easy way to read comp.soft-sys.sas and search the archives.
