Hi all,

I am beginner SAS, I got confused with some of the terms in SAS :
1) observations
2) Records
3) Statements

It depends a lot on context.
Of those, STATEMENT is the only one with a specific SAS definition. Other ones are functions and routines.
Here’s a list of documented SAS Statements, there are more, see the link regarding STATEMENTS documented elsewhere.
The official SAS definition is:
Definition of Statements
A SAS statement is a string of SAS keywords, SAS names, special characters, and operators that instructs SAS to perform an operation or that gives information to SAS. Each SAS statement ends with a semicolon.
All of of this is in the documentation and the first programming course is free.
Hi:
As Reeza explained, much of this is in the documentation. Please look at this web page: http://go.documentation.sas.com/?docsetId=lrcon&docsetTarget=n1rwem8pleuq62n1guwd91poym5p.htm&docset... and at the illustration on the web page, as shown below:
And, this same information is conveyed in Programming 1 in Lesson 3, in the video entitled Examining SAS Data Sets, as shown below, starting at time stamp 00:11 -- The video explains that more common/relational terms are observations=rows and variables=columns. In the old mainframe days, we used to refer to "records" and "fields" which were essentially the same as rows and columns. record=row=observation and field=column=variable...it just depends on your vintage of describing tables or data sets or files.
I hope this points you toward an understanding.

I agree with the recommendations provided by @novinosrin and @Reeza, but there is definitely a distinction in SAS between records and observations.
Throughout the documentation records is used to describe the raw data being read into SAS, while observations is used to describe the individual rows of a SAS dataset. see, e.g., http://documentation.sas.com/?docsetId=basess&docsetTarget=n068wqvbjnndvjn17mqpoxdj7te7.htm&docsetVe...
