As this is the first day, I have lots of enthusiasm to cover lot of topics. I started with the naming convention that can be used in SAS.The names of SAS libraries,data sets and files can only allow _, alphabets(upper and lower case) and underscore('_').
Second topic i covered was related to the log messages and execution of SAS programs. SAS executes programs in steps. It will start executing once it encounters PROC,DATA or RUN keywords in one go and waits till it encounters next PROC, DATA or RUN keyword. The log has data and descriptor portion. The descriptor by name has the descriptive portion relating to the data set and the data portion displays the data.
Third topic is related to the options keyword , which helps in displaying results with or without date, page numbers and number of results to display.And finally i have learnt about "firstobs" and "obs" which helps in displaying results selectively when u have lots of data.
