What is the .LST File Extension?

.LST File Extension Description:

SAS is an integrated system of statistical software comprising the programming SAS language for data management and the data analysis and reporting of SAS procedures. Its CUNIX cluster release is available under the batch mode of UNIX and X-Windows environment.

In this batch mode, the SAS commands are executed from one file with the SAS file extension and its output are directed to two other files with the same name as the input file but with the file extension LOG which contains messages and notes generated by the program and the file extension LST which contains output from SAS procedures creating the printed results.

After the completion of a SAS statement (program) with the UNIX editor and the issuance of the SAS command "sas" at the assigned UNIX prompt, the results from SAS procedures appear in files with the .lst file extension. These files can then be viewed using the SAS editor or via typing the "command: more filename.lst".

In the interactive mode of X-Windows, the SAS statements including the SAS run command are typed in the program editor window to have them executed and then submitted by pulling the Locals menu. Messages and error statements appear in the log window while the output is displayed in the interactive output window. However, the results of SAS procedures in the interactive mode are not automatically saved to files with the .lst file extension; they have to be saved manually.

In a server environment, SAS programmers have to continually work with these three files of SAS: the SAS program file with the .sas file extension, the log file with the .log file extension and the output list file with the .lst file extension. All these three files have to be stored on the UNIX server so that SAS can complete its programming task which involves the opening, editing, and saving of program files, running them on the UNIX system, then opening and analyzing the updated files with the .log file extension and files with the .lst file extension.

This programming cycle of SAS mainly includes the three file operations of OPEN, SAVE, and RELOADS, which are repeated in continuous number of times during the SAS program development.
