SAS Options – Versatile Players in the Game of SASDenise Poll, SAS Institute Inc.
Back in the “Day”
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
Game Plan Basics
Interfaces
Tricks of the game
Acknowledgements and Questions
Basics of Syntax
Syntactically speaking ---
Name and Value combination
» Option METAPORT = 8561 ; /* Numeric */
» Option NOFMTERR; /* Boolean */
» Option CMPLIB = sasuser.funcs; /* Character */
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
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);
Comparisons Statement
Statement options – control the action of the statement in which they appear
Specify using Proc Print data=study (FIRSTOBS = 20);
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;
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

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
Getoption - Default and Startup ValuesSAS -YEARCUTOFF 19991 Options YEARCUTOFF = 1950;
2 %put Returns Just the Option Value: %sysfunc(Getoption(YEARCUTOFF)) ;
Returns Just the Option Value: 1950
9 %put Returns Name and Default Value: %sysfunc(Getoption(YEARCUTOFF, KEYWORD, DEFAULTVALUE)) ;
Returns Name and Default Value: YEARCUTOFF=1920
1 %put Returns Name and Startup Value:10 %sysfunc(Getoption(YEARCUTOFF, KEYWORD, STARTUPVALUE)) ;
Returns Name and Startup Value: YEARCUTOFF=1999
Getoption - Tattle Tail Feature
7 %put Identifies current value setting interface:8 %sysfunc(Getoption(YEARCUTOFF, HOWSET)) ;
Identifies current value setting interface: SAS Session Startup Command Line
GETOPTION Function – Programmatic Use!Sas –orientation portrait
Options Orientation = LANDSCAPE ;
%let setopt = %sysfunc(GETOPTION
(Orientation, KEYWORD, STARTUPVALUE));
Options &setopt; /* Orientation=PORTRAIT */
Getoption Formatting Options 15 %put Option Value: %sysfunc(Getoption(SASAUTOS));Option Value: ( "!sasroot\.....\auto\en" "!sasroot\....\testauto" )
16 %put Expand Environment Variables in Option Value:17 %sysfunc(Getoption(SASAUTOS, EXPAND)) ;
Expand Environment Variables in Option Value: ("C:\SASv9\....auto\en""C:\SASv9\....testauto" )
18 %put Option Value: %sysfunc(Getoption(OBS));Option Value: 9223372036854775807
19 %put Return numeric value with commas:20 %sysfunc(Getoption(OBS, LOGNUMBERFORMAT)) ;Return numeric value with commas: 9,223,372,036,854,775,807

OPTION and GROUP

LISTGROUPS - displays options in each group

RESTRICT – are restricted
LISTRESTRICT – can restrict
Proc Options - Display Option Values

ORIENTATION=PORTRAIT Orientation to use when printing
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
Option Properties
Proc Options Option=AUTOEXEC DEFINE ;
Group= ENVFILES
Group Description: SAS library and file location informationType: The option value is of type CHARACTERMaximum Number of Characters: 1024
More Information – Option DEFINEWhen Can Set: Environment Startup or Session Startup onlyCasing: The option value is retained with original casingQuotes: If present during "set", start and end quotes are removedRestricted: Your Site Administrator cannot restrict modification of this optionOptsave: Proc Optsave or command Dmoptsave will not save this option
Proc Options Define For A Numeric Option
Proc Options Option=OBS Define ; run;… Range of Values: The minimum is 0 and the maximum is 9223372036854775807 Valid Syntax(any casing): MIN|MAX|n|nK|nM|nG|nT|hexadecimal Numeric Format: Usage of LOGNUMBERFORMAT impacts the value format <<<Adds commas
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
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
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
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…
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
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….
Restricted Options
Proc Options LISTRESTRICT; /* CAN restrict */
Proc Options RESTRICT; /* IS restricted */

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;
Verbose Option – Old Style
