first of all data will be available on input stack...Once program reaches the input stack,SAS transforms the stream of characters into indivdual tokens..these tokens are transferred into diffrent parts of SAS for processing such as datastep compiler and the macro processor...The process that SAS uses to extract words and symbols from the input stack is called TOKENIZATION .Tokenization is performed by a compnent of SAS called WORD SCANNER..The word scanner starts the first character in the input stack and examines each character in turn..then it will be analysed by datastep compiler untill it reaches the end of the datastep(run statement)..data step compiler and SCL compiler transforms this output into DISPLAY MANAGER...
