[3] SAS programs have DATA steps, which retrieve and manipulate data, PROC (procedures) which analyze the data, and may also have functions. [4] Each step consists of a series of statements. [5]
Base SAS is a fourth-generation procedural programming language designed for the statistical analysis of data. [ 7] It is Turing-complete and domain specific, with many of the attributes of a command language. As an interpreted language, it is generally parsed, compiled, and executed step by step. [ 8] The SAS system was originally a single ...

In computing, Serial Attached SCSI ( SAS) is a point-to-point serial protocol that moves data to and from computer-storage devices such as hard disk drives and tape drives. SAS replaces the older Parallel SCSI (Parallel Small Computer System Interface, usually pronounced "scuzzy" [ 3][ 4]) bus technology that first appeared in the mid-1980s.
In communications messages, a date-time group ( DTG) is a set of characters, usually in a prescribed format, used to express the year, the month, the day of the month, the hour of the day, the minute of the hour, and the time zone, if different from Coordinated Universal Time (UTC).

In traditional American usage, dates are written in the month–day–year order (e.g. August 14, 2024) with a comma before and after the year if it is not at the end of a sentence [ 2] and time in 12-hour notation (1:50 pm). International date and time formats typically follow the ISO 8601 format (2024-08-14) for all-numeric dates, [ 3] write ...
Unix time is currently defined as the number of non-leap seconds which have passed since 00:00:00 UTC on Thursday, 1 January 1970, which is referred to as the Unix epoch. [ 3] Unix time is typically encoded as a signed integer . The Unix time 0 is exactly midnight UTC on 1 January 1970, with Unix time incrementing by 1 for every non-leap second ...
