/*	SAS OPTIONS ---

	There are literally hundreds of options in SAS that control 
	everything about the SAS environment.  The most commonly 
	used options control formatting of printed output, such as 
	the number of columns per line (LINESIZE or LS) and the 
	number of lines per page (PAGESIZE or PS).  Other options 
	control whether the date is printed on output (DATE or 
	NODATE), whether the printed output is centered (CENTER or 
	NOCENTER), how many observations to read (OBS) and where 
	the first observation starts (FIRSTOBS).

	There are defaults assigned to most options, but all options 
	can be overridden with an OPTIONS statement.  Options that 
	you change with an OPTIONS statement are in effect until you 
	change them with another OPTIONS statement or until SAS ends.  
	In SAS for Windows, the LINESIZE and PAGESIZE options are 
	functions of the font size that is used.  To see what the 
	default options are, run PROC OPTIONS.  Results are printed 
	to the SAS log.
*/

proc options; 
run;

/*
	Note the options that start with "WORK".  The WORK option 
	refers to the location of a directory or folder (a SAS 
	library) where SAS temporary files are stored and is assigned 
	by default.  Other WORK related options control whether the 
	files in the WORK library are erased when SAS starts up and 
	when SAS ends.

	If we wish to change several options, we can do it in one 
	OPTIONS statement:
*/

options ls=75 ps=60 nocenter nodate;
proc options;
run;

/* 
	These options are now set for the remainder of our SAS session,
	or until we change them.

	Options can also be reviewed and changed from the SAS menus.  
	Go to "Tools" -> "Options" -> "System".
