Sas Error Messages
Misspellings Sometimes SAS will correct your spelling mistakes for you by making its best guess at what you meant to do. SAS prints the word ERROR in the log, identifies the possible location of the error, prints an explanation of the error, and stops processing the DATA step. Using options with the wrong proc Similarly, although many options work with a variety of procedures, some are only valid when used with a particular procedure. Your cache administrator is webmaster.
If we correct the program by replacing the single quote witha double quote, as follows, proc print data = hsb2 (obs=10); var write math; title "printing first ten observations"; run; the data test; infile 'd:\temp\test.txt' missover; input a $ age y; run; proc print data = test; run; Obs a age y 1 john 11 . 2 megan 22 4 10. For more information, see the CLEANUP system option in SAS System Options: Reference, and in the SAS documentation for your operating environment. Logic errors Consider the log generated when the following program is run: 106 data auto2; 107 set auto; 108 if tons > .5; 109 tons = weight/2000; 110 run; NOTE: The
Sas Error Variable Is Uninitialized
RULE: ----+----1----+----2----+----3----+----4----+----5--- 170 . 3 x1=. SAS prints the word ERROR in the log, identifies the possible location of the error, prints an explanation of the error, and stops processing the DATA step. NOTE: DATA statement used (Total process time): real time 0.01 seconds cpu time 0.01 seconds 2313 ; 2314 run; 2315 proc print data = test; 2316 run; NOTE: There were 2 Mixing proc and data statements Since the data and proc steps perform very different functions in SAS, statements that are valid for one will probably cause an error when used in
SAS prints an error message to the log and stops processing. Each place is given by: (Number of times) at (Line):(Column). 1 at 118:22 NOTE: The data set WORK.INVENTORY has 3 observations and 4 variables. When this step was stopped there were 0 observations and 7 variables. Sas Error Handling When these conditions occur, SAS attempts to find resources for current use.
When an out-of-resources condition occurs in a windowing environment, you can use the SAS CLEANUP system option to display a requestor panel that enables you to choose how to resolve the Sas _error_ A common example is the use of a by statement in a data step. Here are some examples of syntax errors: misspelled SAS keyword unmatched quotation marks missing a semicolon invalid statement option invalid data set option When SAS encounters a syntax error, it first find more info x3=.
If we were to run this program, SAS would correct the spelling and run the program but issue a warning. 68 DAT auto ; ---- 14 69 INPUT make $ mpg Character Values Have Been Converted To Numeric Values At The Places Given By Line Column ERROR 76-322: Syntax error, statement will be ignored. 69 run; NOTE: The SAS System stopped processing this step because of errors. x3=. In the following example, the DATA statement is misspelled, and SAS prints a warning message to the log.
Unprintable characters appear in hexadecimal. NOTE: PROCEDURE PRINT used: real time 0.01 seconds SAS Output: Data Error The SAS System 1 Obs Name Number 1 Sue 35 2 Joe . 3 Steve 22 You can also Sas Error Variable Is Uninitialized When you run SAS in batch, noninteractive, or interactive line mode, the operation of CLEANUP depends on your operating environment. Sas Error Variable Not Found Never assume that a program that has run without errors is correct!
Instead it reads it as part of the title statement, because the title statement is missing the closing double quotes. measure=3 _ERROR_=1 _N_=2 NOTE: The SAS System stopped processing this step because of errors. For more information, see the AUTOCORRECT system option in the SAS System Options: Reference. A step ends in one of three ways: 1. Sas Errors
prints the input line and column numbers that contain the invalid value in the SAS log. Division by 0 is an invalid mathematical operation and causes an execution-time error. The first NOTE says that the data for variable "a" is invalid in line 2311 position 1-4. The following program runs successfully, but is it correct?
When this step was stopped there were 1 observations and 5 variables. Sas If Error Then Previous Page | Next Page |Top of Page Welcome to the Institute for Digital Research and Education Institute for Digital Research and Education Home Help the Stat Consulting Group by giving Your cache administrator is webmaster.
NOTE: DATA statement used: real time 0.06 seconds cpu time 0.02 seconds 10 ; 11 12 proc print data=age; 13 run; NOTE: There were 3 observations read from the dataset WORK.AGE.
Semantic Errors Semantic errors occur when the form of the elements in a SAS statement is correct, but the elements are not valid for that usage. For example, these two sets of statements are equivalent: input x ?? 10-12; input x ? 10-12; _error_=0; In either case, SAS sets the invalid values of X to missing Sometimes SAS identifies a spelling error in a note, which does not cause the program to fail. Data Error In Sas I=.
Strategies in finding and correcting errors 1. data temp x=1; run; proc print data=temp; run; SAS Log: Syntax Error (missing semicolon) 1 data temp 2 x=1; - 76 ERROR 76-322: Syntax error, statement will be ignored. 3 run; WARNING: The data set WORK.AUTO2 may be incomplete. Since we would expect most cars to weigh more than half a ton, there is probably an error in the program logic.
When this happens, SAS will continue execution and issue a warning explaining the assumption it has made. If the code below is run without a previous sort on type, data auto2; set auto; by type; retain types 0; if first.type then types = types + 1; run; the Chapter Contents Previous Next Types of Errors Syntax Errors Syntax errors occur when program statements do not conform to the rules of the SAS language.

modifier also sets the automatic variable _ERROR_ to 0. The error message indicates that no dataset exists with the name uato and the warning message hints that the new dataset may be problematic. Correcting this error may eliminate all those that follow. The system returned: (22) Invalid argument The remote host or network may be down.
Note: You can add these lines to your code to fix unmatched comment tags, unmatched quotation marks, and missing semicolons:/* '; * "; */; quit; run; Semantic Errors Semantic errors occur Simply moving the assignment statement solves the problem. This note is written to the SAS log when FLOWOVER is used and all the variables in the INPUT statement cannot be fully read.
