SAS System Options in the UNIX environment

Question:
How do I specify SAS system options in the UNIX environment?

Answer:
How you specify SAS system options depends on how you use SAS in the UNIX environment.
If you use SAS via an X-terminal or X-terminal emulation software such as Exodus or MacX, the command to launch SAS on ITS UNIX systems is
/usr/local/sas/sas

SAS system options are preceded by a hyphen and immediately follow the SAS command. For example, if you want to have SAS write its work files (including temporary datasets) to a directory called "mysasdir" located one level below your own current working directory, the syntax for invoking this option would be:

/usr/local/sas/sas -work ./mysasdir

If you use the SAS display manager system via a vt100 terminal interface such as telnet, the usual command to launch SAS is:
/usr/local/sas/sas -fsd ascii.vt100

The -fsd portion of this command is a SAS option which means "full screen device". You could add another SAS system option to this command, such as the -work option mentioned above:
/usr/local/sas/sas -fsd ascii.vt100 -work ./mysasdir

If you run SAS noninteractively by supplying the SAS program file "mysasprog" in the current directory, you would change your command from:
/usr/local/sas/sas mysasprog
to:
/usr/local/sas/sas -work ./mysasdir mysasprog

This would direct SAS to write any work files to the "mysasdir" directory as it processes the contents of your SAS program "mysasprog".

Each of these examples assumes you want to use a particular SAS system option once or a few times. If you intend to use a SAS system option repeatedly, it can be a nuisance to specify the same option each time you invoke SAS. For this type of situation, you can copy the config.sas612 file located in the /usr/local/sas/sas612 directory and edit it using a UNIX text editor.

The config.sas file is a SAS configuration file that contains default settings for a number of SAS system options; you may change the default settings of these options as well as delete or add options of your choosing to this file. If you then launch SAS from the same directory as the config.sas612 file, SAS will use those options.

    Hello,

    I'm looking for some information to learn OLAP in SAS. I have access to SAS Enterprise Guide 4.1 and would like some tutorials to learn SAS Business Intelligence. Anybody out there with some ideas?
    Thanks.

SAS Interview Questions and Answers: CDISC, SDTM and ADAM etc

-
1) What do you know about CDISC and its standards? CDISC stands for Clinical Data Interchange Standards Consortium and it is developed keeping in mind to bring great deal of efficiency in the entire drug development process. CDISC brings efficiency to the entire drug development process by improving the data quality and speed-up the whole drug development process and to do that CDISC developed a series of standards, which include Operation data Model (ODM), Study data Tabulation Model (SDTM) and the Analysis Data Model ADaM ). 2) Why people these days are more talking about CDSIC and what advantages it brings to the Pharmaceutical Industry? A) Generally speaking, Only about 30% of programming time is used to generate statistical results with SAS®, and the rest of programming time is used to familiarize data structure, check data accuracy, and tabulate/list raw data and statistical results into certain formats. This non-statistical programming time will be significantly reduced...

Comparing Two Methods for Removing Formats and Informats in SAS: DATA Step vs. PROC DATASETS

-
Comparing Two Approaches to Removing Formats and Informats in SAS Comparing Two Approaches to Removing Formats and Informats in SAS When working with SAS datasets, there are times when you need to remove formats and informats that have been previously assigned to variables. Two primary approaches can be used for this task: Using the DATA Step Using the PROC DATASETS Procedure This article compares and contrasts these two approaches to help you determine which method is most appropriate for your needs. Approach 1: Using the DATA Step The DATA step is a versatile and commonly used method for removing formats and informats. By assigning variables to a null format or informat, you can effectively remove these attributes from your dataset. Example: data mydata_clean; set mydata; format _all_; informat _all_; run; In this example, the mydata dataset is processed in the DATA step, and...

Studyday calculation ( --DY Variable in SDTM)

-
USE OF THE “STUDY DAY” VARIABLES The permissible Study Day variables (--DY, --STDY, and --ENDY) describe the relative day of the observation starting with the reference date as Day 1. They are determined by comparing the date portion of the respective date/time variables (--DTC, --STDTC, and --ENDTC) to the date portion of the Subject Reference Start Date (RFSTDTC from the Demographics domain). The Subject Reference Start Date (RFSTDTC) is designated as Study Day 1. The Study Day value is incremented by 1 for each date following RFSTDTC. Dates prior to RFSTDTC are decremented by 1, with the date preceding RFSTDTC designated as Study Day -1 (there is no Study Day 0). This algorithm for determining Study Day is consistent with how people typically describe sequential days relative to a fixed reference point, but creates problems if used for mathematical calculations because it does not allow for a Day 0. As such, Study Day is not suited for use in subsequent numerical computations...
