  1. SAS Options – Versatile Players in the Game of SAS Denise Poll, SAS Institute Inc.

  2. Back in the “Day”

  3. Today ---1500+ SAS System Options What kinda “stuff” gets customized? • Appearance of SAS output – PDF* options • Handling of files – ENGINE=V9 • Performance related – SORTSIZE= • Security – PDFSECURITY= • Macro - MACRO

  4. Game Plan • Basics • Interfaces • Tricks of the game • Acknowledgements and Questions

  5. Basics of Syntax • Syntactically speaking --- Name and Value combination • Option METAPORT = 8561 ; /* Numeric */ • Option NOFMTERR; /* Boolean */ • Option CMPLIB = sasuser.funcs; /* Character */

  6. Comparisons - System Options • System options – Remain in effect for all DATA and PROC steps unless re-specified • Specify using: • Options statement • Options DATASTMTCHK = ALLKEYWORDS; • Command line and configuration files • -DATASTMTCHK ALLKEYWORDS • Options Window

  7. Comparisons - Data Set • Data set options – apply to the processing of the SAS data set with which they appear. Some data set options are also SAS System options. • Specify using • Data new ; /* Usage of FIRSTOBS overrules any previous setting */ set study ( FIRSTOBS = 5);

  8. Comparisons Statement • Statement options – control the action of the statement in which they appear • Specify using • Proc Print data=study (FIRSTOBS = 20);

  9. Forest For The Trees • If there are over 1500+ SAS System options how do I find the one that I need? • Documentation is always helpful • Proc Options LISTGROUPS; Proc Options;

  10. Logical Groups Proc Options Group=(SORT PERFORMANCE) ; Group=SORT ….. SORTSIZE=0 Size parameter for sort Group=PERFORMANCE …… BUFNO=1 Number of buffers for each SAS data set

  11. DMS Options Window – RMButton to Find by Name

  12. SAS Enterprise GuideTooltip Meaning and Value Completion

  13. SAS System Options Interfaces • GETOPTION function • Proc Options • Command line • Configuration files – Verbose and restricted option files • Options statement • Options window • Procs Optsave and Optload • DMOPTSAVE and DMOPTLOAD • SQL usage

  14. Getoption Function Keywords “Good Golly Miss Molly” • Subset of Return Value Options • DEFAULTVALUE - returns the default option value • STARTUPVALUE - returns value from SAS startup • HOWSET – returns a character string indicating setting interface • Subset of Return Value Formatting Options • EXPAND - WIN and UNIX, expand Environment Variables • KEYWORD - Option Name = Value • LOGNUMBERFORMAT – Numeric option value with “,”s

  15. Getoption - Default and Startup Values

  16. Getoption - Tattle Tail Feature

  17. GETOPTION Function – Programmatic Use! Sas –orientation portrait Options Orientation = LANDSCAPE ; %let setopt = %sysfunc(GETOPTION (Orientation, KEYWORD, STARTUPVALUE)); Options &setopt; /* Orientation=PORTRAIT */

  18. Getoption Formatting Options

  19. A True Classic - Proc Options • OPTION and GROUP • LOGNUMERFORMAT • LISTGROUPS - displays options in each group • DEFINE • VALUE • INSERT, APPEND, LISTINSERTANDAPPEND • EXPAND • RESTRICT – are restricted • LISTRESTRICT – can restrict

  20. Proc Options - Display Option Values • Proc Options Option=(OBS ORIENTATION) >1 specified LOGNUMBERFORMAT; OBS=9,223,372,036,854,775,807 Number of the last observation to process ORIENTATION=PORTRAIT Orientation to use when printing

  21. Again -- Logical Groups Proc Options Group=(SORT PERFORMANCE) ; Group=SORT ….. SORTSIZE=0 Size parameter for sort Group=PERFORMANCE …… BUFNO=1 Number of buffers for each SAS data set

  22. Option Properties • Proc Options Option=AUTOEXEC DEFINE ; Group= ENVFILES Group Description: SAS library and file location information Type: The option value is of type CHARACTER Maximum Number of Characters: 1024

  23. More Information – Option DEFINE When Can Set: Environment Startup or Session Startup only Casing: The option value is retained with original casing Quotes: If present during "set", start and end quotes are removed Restricted: Your Site Administrator cannot restrict modification of this option Optsave: Proc Optsave or command Dmoptsave will not save this option

  24. Proc Options Define For A Numeric Option

  25. Tattle Tail Feature – Value Keyword The GETOPTION function has the HOWSET keyword Proc Options uses the “VALUE” keyword to identify what interfaces set the option value • Some interfaces are: • command line, Config file(s), Options statement….. • Options that can “add to” an option value • INSERT= and APPEND= Options

  26. Proc Options Simple Usage – Value Keyword Proc Options option=sasautos VALUE ; run; Option Value Information For SAS Option SASAUTOS Value: ( "!sasroot\.... " "!sasroot\....\testauto“ ) How option value set: Config File Config file name: C:\SASv9\tmp\SASv9-1068.cfg << Version 9.3

  27. INSERT and APPEND SAS Options • Some options support adding to the option value using INSERT and APPEND Example: Config File contains: -Append AUTOEXEC myconfigAUTO.sas Command line contains: -Append AUTOEXEC mycmdAUTO.sas Result: myconfigAuto.sas mycmdAUTO.sas

  28. Insert and Append Options Proc Options LISTINSERTAPPEND; run; • Core options: INSERT and APPEND • AUTOEXEC Identifies AUTOEXEC… • CMPLIB Identify previously… • FMTSEARCH List of catalogs to… • MAPS Location of maps for… • SASAUTOS Search list for autocall… • SASHELP Location of the…

  29. Proc Options – Value Keyword Proc Options Option=AUTOEXEC VALUE; Value ('!mydir\twoAuto.sas‘ '!mydir\twoAuto.sas‘) How option value set: Config File Value Inserted: '!mydir\twoAuto.sas' Config file name: U:\config2.cfg   How option value set: Config File Value Inserted: '!mydir\oneAuto.sas' Config file name: C:\MySAS\ConfigDNT.cfg

  30. Expand Environment Variables Expansion of environment variables in the physical name …same support that we saw earlier with the GETOPTION function Proc Options Option=SASHELP EXPAND ; Without Expand: myval = ("!sasroot\sas… With Expand: myval = ("C:\SASv9\sas….

  31. Restricted Options • Proc Options LISTRESTRICT; /* CAN restrict */ • Proc Options RESTRICT; /* IS restricted */ 3 Configuration File 2SAS Command 1 Site Restricted Configuration File

  32. Restricted Options Output Proc Options LISTRESTRICT; run; Your Site Administrator can restrict the ability to modify the following Portable Options: APPLETLOC Location of Java applets ... BUFNO Number of buffers for each SAS data set BUFSIZE Size of buffer for page of SAS data set ... CGOPTIMIZE Control code generation optimization ... COMAMID Specifies the communication access….

  33. Saving and Loading Option Values • Procedures OptSave and OptLoad • What options cannot be saved? • Session startup options • Password options Proc Optsave Data=WORK.saveopts; NOTE: The data set …. has 262 observations and 2 variables. Proc Optload Data=WORK.saveopts;

  34. Verbose Option – Old Style sas -verbose ==== Processed Configuration File(s) ==== C:\SASv9\tmp\SASv9-5776.cfg ==== Environment Variable Options ==== <none> Option Value ====== ===== MAPS "!sasroot\sasgen\....en\maps" SASAUTOS "!sasroot\sas\.....\auto\en"

  35. Verbose Option – New for 9.3 sas -verbose --------------------------------------------------------------- Options specified on the command line: --------------------------------------------------------------- SASHOST = C:\....dll DMS….. --------------------------------------------------------------- Options specified in the config file C:\SASv9\… --------------------------------------------------------------- SASAUTOS = ( !sasroot\....) SASHELP= ( !sasroot\....)

  36. Acknowledge and Question Bravo to my fellow portable and host developers, testers and writers who collaborate to bring SAS system options to customers. Questions?
