Posted AM views In reply to Steve Input buffer refers to a logical concept not a physical storage area. It is also a logical concept and created after input offer. A format is a layout specification for how a variable should be printed or displayed. Assume we create a SAS data set in a data step, and include the following line in the data step.

Column input — SAS Input Method, allows you to read variable values that occupy the same columns within each record. As you know, to use column input , we simply list the variable names in the INPUT statement, immediately following each variable name with its corresponding column positions in each of the data lines. You must use an assignment statement to store that value in a variable. The INPUT statement uses an informat to read a data value and then optionally stores that value in a variable.

For numeric and character variables, this constant is the maximum number of bytes stored in the variable. For numeric variables, 2 to 8 bytes or 3 to 8 bytes, depending on your operating environment. Use separate DATA steps to enter multiple sets of data. One of the most common ways to read data into SAS is by reading the data instream in a data step — that is, by typing the data directly into the syntax of your SAS program.

This approach is good for relatively small datasets. Spaces are usually used to "delimit" or separate free formatted data. The physical name is the name that the operating environment uses to access the file. 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:. When a variable value contains the delimiter and DSD is used in the FILE statement, the variable value will be enclosed in double quotation marks when the output is generated. For example, the following code. If a quoted text string contains the delimiter and DSD is used in the FILE statement, then the quoted string will not be enclosed in double quotation marks when used in a PUT statement.

When you write data to the output file, SAS transcodes the data from the session encoding to the specified encoding. You supply the variable name; SAS automatically assigns the value. You supply the variable name; SAS assigns the value of the number of lines left on the current page to that variable.

Operating Environment Information: Values for logical-record-length are dependent on the operating environment. The system can move back and forth between the number of lines that are specified while composing them before moving on to the next set.

It defines the structure of the data component and holds the results of the DATA step and binds that component to a table definition to produce an output object. Without suboptions, the default table definition uses the variable's label as its column heading.

If no label exists, the definition uses the variable's name as the column heading. In such a case, SAS discards the data item that exceeds the current line length, writes the portion of the line that was built before the error occurred, and issues an error message. 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.

Use the FILE statement to route this output to either the same external file to which procedure output is written or to a different external file. You can indicate whether carriage-control characters should be added to the file. See the SAS documentation for your operating environment before you use this statement. This functionality is briefly discussed here. Follow these guidelines:. Any such options that are used in the FILE statement are ignored.

This character variable is automatically retained and initialized to blanks. The following two methods are available:. The assignment statement updates the contents of the current output buffer and sets the buffer length to the length of 'string-in-quotation-marks' or character-expression.

However, using an assignment statement does not affect the current column pointer of the PUT statement. In the following example, the assignment statement updates the contents of the current output buffer. The column pointer of the PUT statement is not affected:. SAS creates the following output: This is from both, sir. Y is first assigned Something is here then Y is assigned is here. Write a report. Route output to the SAS output window. Point to the header information.

Write a header on each page. These statements execute each time a new page is begun. Route output to the standard SAS output window.
