Option AUTOSAVELOC

Information:Specifies a place of a Program Editor autosave file. If we wish to autosave a SAS programs youare now operative on, this choice has to be used.
Syntax: AUTOSAVELOC= “destination”Usage: options AUTOSAVELOC= “C:SASSas Codes”;Default: Enabled – 10 MinutesAdditional Info:To safeguard which we do not remove any of your work in a Program Editor, SAS can automatically save yourfiles during an interlude we specify. The interlude can operation from 0 (Autosave off) to 480 minutes. The defaultinterval is 10 minutes. The autosave record is saved as pgm.asv in a stream printed matter or in a locationspecified by a AUTOSAVELOC complement option.
To capacitate or invalidate autosave as well as set a interval:
Select Tools->Options->Preferences->Edit tab
Select or deselect Autosave every.
Set a interlude by typing a series in between 1 as well as 480 in a minute’s box.
You can additionally operate a WAUTOSAVE authority to enable, disable, as well as set a interval. WAUTOSAVE
INTERVAL=minutes will spin upon autosave regulating mins as a interval.

Option DATASTMTCHK

Information:It is probable to clean out unintentionally an submit interpretation set when we replace a semicolon upon a DATA statement. If a subsequent matter is SET, MERGE, or UPDATE, a strange interpretation set is overwritten. Different, though significant, problems movement when a subsequent matter is RETAIN. DATASTMTCHK= enables we to strengthen yourself opposite overwriting a submit interpretation set.
Syntax: DATASTMTCHK=COREKEYWORDS ALLKEYWORDS NONEUsage: OPTION DATASTMTCHK = COREKEYWORDSDefault: OPTION DATASTMTCHK = COREKEYWORDS

Option CLEANUP

Information:Specifies which during a finish session, SAS attempts to perform automatic, successive clean-up ofresources which have been not compulsory for execution. Nonessential resources embody those which have been not visibleto a user (for example, cache memory) as well as those which have been manifest to a user (for example, a KEYSwindows).When CLEANUP is in outcome as well as an out-of-resource condition occurs (except for a disk-full condition), arequestor window is not displayed, as well as no involvement is compulsory by a user. When CLEANUP is ineffect as well as a disk-full condition occurs, a requester window displays which allows a user to confirm howto proceed.
Syntax: CLEANUP NOCLEANUPUsage: options CLEANUP;Default: NOCLEANUP

Option FMTSEARCH

Information:When SAS finds a anxiety to a user-defined format or informat, it will demeanour for a format catalogue called work.Formats. If it finds no such format catalog, or if it does not find a user-defined format in which catalog, it will demeanour for a catalogue called library.Formats. If it has no fitness there, SAS will go no serve unless we discuss it it where to look. If we name a format catalogue anything alternative than Formats or store it in a living room with a libRef alternative than library, we will need to operate a fmtSearch= choice to discuss it SAS where to find a formats. List a format catalogs in parentheses starting with a a single we wish to poke first. SAS searches a format catalogs in a sequence listed, until a preferred partial of is found. The worth of a catalogue selection can be possibly a libRef or libRef.catalog. If usually a libRef is given, SAS assumes which Formats is a catalogue name.
Syntax: FMTSEARCH=(catalog-specification-1… catalog-specification-n) Usage: options FMTSEARCH=(catalog1 catalog3 catalog3); Default: It searches in all catalogs available. If work as well as living room have been not partial of a catalogs list specified, they have been searched first.

Option NOERRORABEND

Information:The complement choice ERRORABEND forces an abend(Abnormal End) to start usually when a PROC step is active. The ABORT matter is unnoticed in a DATA step below. The complement choice ERRORABEND does not means an abend to start since a PROC step is not active.
Syntax: errorabend Usage: options errorabend; Default: Not Enabled. Additional Info:You can operate a following complement options to carry out blunder doing (resolve errors) in your program:
BYERR – specifies either SAS produces errors when a SORT procession attempts to routine a _NULL_ interpretation set.
DKRICOND – specifies a turn of blunder showing to inform when a non-static is blank from an submit interpretation set during a estimate of a DROP=, KEEP=, as well as RENAME= interpretation set option.
DKROCOND – specifies a turn of blunder showing to inform when a non-static is blank from an outlay interpretation set during a estimate of a DROP=, KEEP=, as well as RENAME= interpretation set option.
DSNFERR – when a SAS interpretation set cannot be found, specifies either SAS issues an blunder message.
ERRORABEND-specifies either SAS responds to errors by terminating.
ERRORCHECK- specifies either SAS enters syntax-check mode when errors have been found in a LIBNAME, FILENAME, %INCLUDE, as well as LOCK statements.
ERRORS-specifies a extent series of observations for which SAS issues finish blunder messages.
FMTERR-when a non-static format cannot be found, specifies either SAS generates an blunder or continues processing.
INVALIDDATA-specifies a worth which SAS assigns to a non-static when shabby numeric interpretation is encountered.
MERROR-specifies either SAS issues a notice summary when a macro-like name does not compare a macro keyword.
SERROR-specifies either SAS issues a notice summary when a macro non-static anxiety does not compare a macro variable.
STEPCHKPT-specifies either checkpoint-restart interpretation is to be available for a collection program.
STEPCHKPTLIB-specifies a libref of a living room where checkpoint-restart interpretation is saved.
STEPRESTART-specifies either to govern a collection module by regulating checkpoint-restart data.
VNFERR-specifies either SAS issues an blunder or notice when a BY non-static exists in a single interpretation set though not an a single some-more interpretation set when estimate a SET, MERGE, UPDATE, or MODIFY statements.

Option MSGLEVEL=

Information:Controls a turn of item in messages which have been created to a SAS log.
Syntax: MSGLEVEL= N we (N-Prints notes, warnings, as well as blunder messages only. I-prints a single some-more records regarding to index usage, combine processing, arrange utilities, as well as CEDA usage, along with customary notes, warnings, as well as blunder messages.)) Usage: options msglevel=i; Default: N. Additional Info:If msglevel=i, It will be utilitarian in cases like…
SAS writes a notice to a SAS record when a MERGE matter would means variables to be overwritten
SAS writes a summary which indicates which classification product was used.
SAS writes a summary which indicates when CEDA (Cross Environment Data Access) is being used to routine a SAS file.

Option REALMEMSIZE

Information:Indicates a volume of practical mental recall SAS can design to allocate. Use a REALMEMSIZE complement choice to optimize a opening of SAS procedures which change their algorithms as well as mental recall usage. Setting a worth of REALMEMSIZE as well low or as well tall might outcome in reduction than optimal performance.
Syntax: -REALMEMSIZE n nK nM nG hexX MIN MAX Usage: options -REALMEMSIZE MAX; Default: 0.Determined by SAS when SAS starts

Option SLEEPWINDOW

Information:Enables or disables a SLEEP window. The SLEEP window appears when a SLEEP duty or a WAKEUP duty suspends a execution of a DATA step. The SLEEP window displays a time which stays prior to a DATA step starts running.
Syntax: -SLEEPWINDOW -NOSLEEPWINDOW Usage: options -SLEEPWINDOW; Default: Enabled.

Option INVALIDDATA

Information:Specifies a worth SAS is to allot to a non-static when shabby numeric interpretation have been encountered. The INVALIDDATA= complement choice specifies a worth which SAS is to allot to a non-static when shabby numeric interpretation have been review with an INPUT matter or a INPUT function.
Syntax: INVALIDDATA=’character’ Usage: options INVALIDDATA=’xyz’; Default: The default worth is a duration (.). Additional Info:The syntax which is shown here relates to a OPTIONS statement. On a authority line or in a pattern file, a syntax is specific to your handling environment. For details, see a SAS support for your handling environment.

Option ERRORS

Information:Controls a extent series of observations for which finish blunder messages have been printed. If interpretation errors have been rescued in some-more than n observations, estimate continues, though blunder messages do not imitation for a a single some-more errors. Note: If we set ERRORS=0 as well as an blunder occurs, a note displays in a record which states which a extent set by a ERRORS choice has been exceeded.
Syntax: ERRORS=n nK nM nG nT MIN MAX hexX Usage: options errors=1; (Prints usually a single blunder as well as a complement stops processing) Default: By default it prints all errors. Additional Info:The syntax which is shown here relates to a OPTIONS statement. On a authority line or in a pattern file, a syntax is specific to your handling environment. For details, see a SAS support for your handling environment.

Option COMPRESS

Information:Controls a application of observations in outlay SAS datasets.
Syntax: COMPRESS=NO YES CHAR BINARY (CHAR BINARY specified application techniques) Usage: options COMPRESS=YES; Default: NO. Additional Info:Compressing a record is a routine which reduces a series of bytes compulsory to paint any observation. Advantages of compressing a record embody marked down storage mandate for a record as well as fewer I/O operations compulsory to review or write to a interpretation during processing. However, some-more CPU resources have been compulsory to review a dense record (because of a beyond of uncompressing any observation), as well as there have been situations when a ensuing record distance might enlarge rsther than than decrease. Use a COMPRESS= complement option
