1 A Flow Chart for Users to Solve SAS Programming Problems Jan Bakker sas log, sample source 3
2 A Panel Controlled Statistical Data Base Application Seppo Rinne A statistical data base application is presented. The base contains monthly and quarterly information on new, effective and terminated employment pensions and the amounts paid. The system is intended for end users. The use of AF-programs and macro facility enables minimun amount of input form the user and requi res no syntactic knowledge for querying and updating the base. During a session, the user may make several queries in sequence. By appropriate location of the invocations of subsequent modules, unnecessary and potentially harmful recursivity can be avoided. The code can be simplified and maintainability increased by feasible organization of the data and by using macro variables for storing layout parameters for each report type. In building the query system, savings can be gained by proper ordering of phases. Introducti on Users of statistical information have traditionally relied on statistical books and other printed material proc step, macro variable, class variable, proc tabulate, macro definition, %if-%then-%else, dataset source 6
3 A Procedure for Documenting and Assessing Bioequivalence Alfredo Ardia,
C. Montoro,
N. Orlando		 Bioequivalence comparative trials are conducted to demonstrate that the bioavailability of new formulations (one or more) of a standard drug does not differ from the original one or that new forms of administration (one or more) do not differ from the actually marketed formulation. The most widely used experimental procedures follows the cross-over scheme in which each subject receives each of the forms of the studied caupound over the course of the study in an order of administration such to generate a design constituted by a series of Latin squares. In alternative, not all of the formulations are given to the same subject but at least two of them conducting in such a way to an incomplete block design. Main response variables on which assessment is based are AUC (area under curve), Cmax (peak level) - observed or log-transformed values - and tmax (time to peak level) data science, confidence interval, proc step, standard deviation source 11

8 Automatic Analysis of Clinical Trials J. C. Peyrieux The analysis of a clinical trial necessitates to issue a wide number of tables, most of them being "standard" tables comparing the different treatments of the trial. A SAS AF prototype has been developped in order to issue automatically these tables in such a presentation that they could be directly incorporated in the report without modifications. Specific tests, some of them depending on the results, are also automatically issued data step, data science, exact test, fisher exact test, proc step, call symput, clinical trial, nominal variable, proc sql, dataset, proc freq, regression analysis source 6

10 Converting Existing Version 5 Applications to Version 6 Craig Drury Bec:ause of the many enhancements available with Version 6 SASfFSIM and SAS/AP software, all Version 5 SAS/FSP and SAS/AF applications need to be converted to Version 6 format In order to be run on a Version 6 system. This paper explains the steps of a conversion and its results, as well as new Version 6 features for enhancing Version 5 applications. Also discussed are the CPORT, CIMPORT, and DOWNLOAD procedures available with base SAS software. Conversion of SAS/AF program screens from Version 5 format to Version 6 format is e~ned in detail, including the various conversion options proc step, sas base source 8

16 GBLAND: A Graphical SAS Macro for Statistical Analysis of Measurement Method Comparison and Measurement Repeatability Bob Day,
Retha Keyser		 Bob Day, S.A.M.R.C. Computing Centre Retha Keyser, S.A.M.R.C. Computing Centre In both clinical and medical research methodology, new measurement techniques are often evaluated by assessment of agreement with an established method. Such studies are often analysed inappropriately, especially by the misleading use of correlation coefficients. In 1983, Bland & Altman published a more appropriate, simple rnd informative graphical analysis which may also be used in th~ssessment of repeatability . This paper describes a. SAS Macro which utilises SAS/GRAPH to make the Bland & Altman analysis quickly and easily available to the MRC's many comparatively inexperienced SAS users. Examples are used to highlight the advantages of the Bland & Altman analysis, together with automatic warnings in circumstances when this method might also prove in valid correlation, sample, confidence interval, sample size, macro definition, macro facility, proc step source 10
17 GPEARSON: A Graphical SAS Macro Using the Pearson Chart or Distribution Characterisation and Transformation Assessment Bob Day,
Retha Keyser		 Bob Day, S.A.M.R.C. Computing Centre Retha Keyser, S.A.M.R.C. Computing Centre Considering the importance of the normality of data for many of the more commonly used statistical analyses, it is surprising how seldom distribution characterisation is carried out. In 1954, Pearson et al drew up an excellent facility! (underutilised to this day by most scientists) which not only assesses the normality of distributions, but also types skewed distributions and indicates the most appropriate expressions for transforming distributions to normality so that further analyses might be valid. This paper describes a SASo Macro which utilises the capabilities of SAS/GRAPHQ to make analyses based on the Pearson Chart quickly and easily available to SAS users group by, proc step source 12

20 Kabivitrum Security Dept Administrative System - A SAS/DMI and SAS/SHARE Application Rein Maasing At KabiVitrum AB the Security Dept keeps data about each employee's doorkeys, Id-CARDS, parking permits etc in a computer system used by four persons simultaneously. Originally the system was written in the IBM/AS-language in a VM/CMS environment. As the data files grew the performance deteroriated. When SAS/SHARE became available the system was rewritten and based on SAS/DMI and SAS/SHARE under MVS. The result was a considerable improvement in performance and reduction of running cost. The company KabiVitrum is a State owned Swedish pharmaceutical company. Our annual turnover is in the magnitude of SEK 2.000 milj. Altogether there are about 2100 people employed in the company. The products are sold through marketing companies in western Europe, United States and Japan.

27 PC Access to SAS Mainframe Graphics Heinz Schaab,
Seigbert Heinecke		 Graphics calculated by SAS on the mainframe are printed on PC periphery and PC screens. It is shown what problems may occur and how they can be solved by simple means. I. The Problems Graphics as shown in figure 1 are very often required in engineering. Most of our en gineers use PCs for their research work. Our problem was to give these engineers access to such graphics. Two was seemed possible: (al Buy some PC software that satisfies our requirements. (b) Transport SAS graphics onto PC screens and PC printers. Choosing (al meant to buy one expensive software license for each PC. Furthermore, we have large data and PC software does not have the desired high performance, especially when mathematical procedures are necessary to evaluate statistical data or to do such work as spline-approximation. Our decision to choose (bl was backed by the fact that most of our PCs are connected to our mainframe by IRMA boards proc sgplot, dataset source 4
28 PETBASE, A Statistical Data Base System for the Anatomically Based Analysis of PET DATA Curt Beil,
H. Bonner,
U. Pietrzyk		 Efficient management and analysis of functional data as obtained with positron emIssion tomography (PET) is essential for reliable interpretation of physiological processes. New multislice imaging systems multiply the amount of available data and emphasize the need for more standardized ways of data analysis. A statistical database was developed for effective management and accessibility of PET data combined with powerful statistical analysis features as provided by SAS . It is based on a anatomical-functional correlative image analysis system, previously reported by our group. Regions of interest templates, defined in normals and individually adjusted, are assigned to larger, standardized brain areas and functional values are stored within the database thus reducing the amount of data proc step, data science source 11

33 SQL and the SAS System Version 6 and Beyond Lewis Church Jr.,
Paul Kent		 This papar provides an overview of Structured Query Language (Sal) and its implementation in Version 6 of the SAse System. The History of SQl The Relational Data Model, proposed by Codd (1970), represents data in tables. Structured Query Language (SOL) is a lenguage used for accessing data stored in tables. The SAS data set con cept blends very nicely with the concept of a table in the relational data model. Both have columns (variables) and rows (observa tions). SAS data sets are a littte more liberal than true relational model tables because they allow duplicate rows and have an inherent ordering. Nevertheless, they are similar enough to make Sal a useful language for accessing SAS data sats. The terms data base table and SAS data set are interchangeable in the con text of this papar. There are many commercial products that support SOL Early Sal-based systems were written for mainframes and minicom puters where statement, order by, proc means, select, proc step, dataset, proc sql source 4

39 Unlimiting a Limited Macro Environment David S. Septoff The full Macro facility provides SA~users with an extremely powerful programming tool. It allows for conditional execution of DATA and o~ PROC steps, creation of parameter driven applications, passing SA:::> variables across steps and much much more. Unfortunately, the full power of Macro is not available in some operating environments. These programmers need not despair. SA~code can be written to simulate SA"ifV Macros using the Base product available on all operating systems. This paper presents an example of a "SA~Macro Based System" developed in a VAX environment and, finally draws some conclusions on how SAS, as a programming language, can be just as powerful in a "partial" Macro environment as it is in a "full" Macro environment proc step, macro facility, macro definition source 9
