$.$ Information Technology Services $($ITS$)$ at Central State University has a computing service called $$the Grid,$$ which is offered to faculty, staff, and students. This supercomputer is a cluster of $10$ computers that, if programmed correctly in a grid environment, can process much faster by distributing the work across $10$ machines. University users that would like to use the Grid computing environment must register with ITS. The raw data file CompUsers.dat contains the variables user ID$,$ classification group $($faculty$,$ staff, or student$),$ first name, last name, email address, campus phone number, and department.

a$.$ Examine the raw data file CompUsers.dat and read it into SAS.

b$.$ Print the data set.

c$.$ Write another DATA step to read the raw data file and remove the student records. Do this as efficiently as possible by testing the classification group as it is being read in with the INPUT statement.

d$.$ Print the data set.Faculty CHARLES PORTER
