Operating Environment Information: Different operating environments call an aggregate grouping of files by different names, such as a directory, a MACLIB, or a partitioned data set.
For details about how to specify external files, see the SAS documentation for your operating environment. Note: Some operating environments do not support pipes. The temporary file can be accessed only through the logical name and is available only while the logical name exists. Operating Environment Information: Additional specifications might be required when you specify some devices. Values in addition to the ones listed here might be available in some operating environments. When you specify DSD, SAS treats two consecutive delimiters as a missing value and removes quotation marks from character values.
When you read data from an external file, SAS transcodes the data from the specified encoding to the session encoding. Like automatic variables, this variable is not written to the data set.
The variable is set only after SAS encounters the next file. Operating Environment Information: Values for line-size are dependent on the operating environment record size. For details, see the SAS documentation for your operating environment. Operating Environment Information: Values for logical-record-length are dependent on the operating environment. When an INPUT statement reaches the end of the current input data record, variables without any values assigned are set to missing.
The absolute maximum depends on your host operating environment. Operating Environment Information: Values for record-format are dependent on the operating environment. Variables without any values assigned are set to missing. You can use the variable in the same way as any other variable, even as the target of an assignment. The variable is automatically retained and initialized to blanks.
See the SAS documentation for your operating environment before using this statement. You can read from multiple input files in a single iteration of the DATA step in one of two ways:. See Reading from Multiple Input Files.
Follow these steps:. Any such options that are used in the FILE statement are ignored. This character variable is automatically retained and initialized to blanks. For example, the following PUT statement writes the contents of the input buffer by using a hexadecimal format.
By default, the delimiter that is used to read input data records with list input is a blank space. To read a value as missing between two consecutive delimiters, use the DSD option. Therefore, a value that is missing between consecutive delimiters is read as a missing value.
For example, this DATA step program uses list input to read data that is separated with commas. The second data line contains a missing value. The second observation is built incorrectly:.
The DSD option also enables list input to read a character value that contains a delimiter within a quoted string. Sign In. Turn on suggestions.

Use data step to import a CSV file with date and time. Posted PM views. Hi, I was trying to import a csv file. A sample data is attached. A more general question is, how to perfectly import such csv files with data step? Re: Use data step to import a CSV file with date and time. Posted PM views In reply to xyxu. The Import Wizard is an easy point-and-click method to import external files.
This will open the Import Wizard. Firstly, you can specify the name and location library of the output dataset. Secondly, you can define the file type you want to import. By default, SAS guesses the file type based on the file extension.
Thirdly, you can tell SAS if your file has a header or not. By default, SAS assumes the file has. If not, uncheck the Generate SAS variable names option. Finally, you can define the first row that contains data and the number of rows SAS needs to read to guess the data type of each variable.
By default, SAS reads 20 rows. As you can see in the table below, SAS misinterpreted the type of some columns. Skip to content. You can probably do a much better job at guessing what data types to use than PROC import can.
You can definitely do a better job of creating meaningul variable names. CARS and read it back in. Check if there is some other output tyep you can save to that will mark the end of lines properly. Or perhaps upgrade the version on Excel? View solution in original post. The data you posted was all on one line, which matches what your SAS log says. If you want SAS to treat it as four lines you need to have line breaks between the lines.
Where did you create the file? Perhaps it is using a non-standard character to indicate the line breaks? In the old days Mac's used to use CR '0D'x as the end of line characters. When I copy and paste the data from TextEdit into a Word file, or an email message, it is in colums and rows See screen shot, lower half. When I paste in into this message it is on one line.
In Excel for Mac. There is no visible line break in the file e. Is there something wrong with the way I am creating the. I simply typed the values into cells and then saved the file as a. When I look more closely at the UCLA data, the non-standard data values are enclosed in quotation marks See screen shot, upper half. Do I need to tell it explicitly?
I'm just playing around at this point.
