Data Structures
•Relative lists: (statically allocated arrays) 
–direct access for retrieve
–problem: searching! Insert might cause the data to be inserted somewhere other than what the position specifies (i.e., if the position # is greater than the next “open” position)
–problem: shifting! Remove, insert alters all subsequent data
–problem: memory limitations (fixed size)
–problem: must “guess” at the SIZE at compile time
