How it's done: 
These programs are grouped together to form two 
subsystems: Search and Retrieval (S & R) and Direct-
Access Data Display (DADDS). The S & R subsystem 
provides the user with the capability to select and 
process variable data without extensive searches. The 
system searches specified data files, sorts the files into a 
specified order, performs simple or complex computa-
tions, prints or displays the results, and updates the 
data base. The DADDS subsystem provides the capability 
to access data files, process data, and present results as
