Sas Variable Is Uninitialized Error
The following example illustrates the "Note: Variable is uninitialized" and "Error: Variable not found" messages SAS displays in the log window to warn you of such problems: First, note that there Regex expression in mapinfo sql to remove special character Draw an hourglass How to search for flights for a route staying within in an alliance? This message occurs when a DATA Step attempts to use a variable which is either not present in the input dataset or has not been created in a preceding step.

Each data, proc and run statement causes the previous step to execute. Correct your programs one step at a time, before proceeding to the next step. SAS encounters the end of the program.
john 11 megan 22 4 data test; infile 'd:\temp\test.txt'; input a $ age y; run; proc print data = test; run; Here is the output from proc print: Obs a age data auto2; set uato; ratio = mpg/weight; run; However, because we misspelled the dataset name in the set statement, the new dataset contains 0 observations. 2 data auto2; 3 set uato; What causes the message? Sas If Error Then The system returned: (22) Invalid argument The remote host or network may be down.
This requires that the data has either been sorted by the variable(s) in the by statement or that the data was read in already sorted. Sas Error Variable Not Found Simply moving the assignment statement solves the problem. 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 Unmatched quotes/comments Unclosed quotes and unclosed comments will result in a variety of errors because SAS will fail to read subsequent statements correctly.
More often, when your program contains spelling errors, the step will terminate and SAS will issue an error statement or a note underlining the word, or words, it does not recognize. Sas Error Handling A perfectly correct statement or option may cause an error not because it is written incorrectly, but because it is being used in the wrong place. 88 proc freq data = Consequently the two correct statements are now errors. 2. This works for uninitialized variables and implicit type conversions.

WARNING: The data set WORK.AUTO2 may be incomplete. Consider the following program, which is correct, except for the missing semicolon: proc print data = auto var make mpg; run; The missing semicolon causes SAS to read the two statements Character Values Have Been Converted To Numeric Values At The Places Given By: (line):(column). The syntax for the following program is absolutely correct, except for the missing semicolon on the comment: * Build a file named auto2 data auto2; set auto; ratio=mpg/weight; run; 34 * The Variable In The Drop Keep Or Rename List Has Never Been Referenced If we check the log, it does not have any blue notes indicating that the code has been executed.
But does it give us the intended result? Once we understand the message, correcting our code is usually simple enough and in this case, we just need to add a dollar sign after variable "a" in the input statement asked 1 year ago viewed 422 times active 1 year ago Linked 1 Warn if column is missing in a data step 2 Detect operation on missing values during SAS datastep Can I use my client's GPL software?

Not sorting data before using statements that require sortAlthough steps are executed independent of each other, some steps require a previous step in order to be carried out properly.

Look for common errors firstMost errors are caused by a few very common mistakes. In this case, we are subsetting on a variable that has not yet been defined. It runs without an error message. Since line 2310 is the line corresponding to the statement "cards;", line 2311 corresponds to the first line of data which starts with input john.
The remaining lines tell us that despite the uninitialized variable, the dataset WORK.CLASS is still created. Because the first semicolon it encounters is after the word auto2. WARNING: Data set WORK.AUTO2 was not replaced because this step was stopped. When this step was stopped there were 6 observations and 16 variables.
