Survo is an integrated system for statistical analysis, computing, data base management, graphics, desktop publishing, etc. Through its unique editorial interface, Survo forms a general environment for many kinds of applications. Technically, Survo is a collection of C programs (modules) with a common interface established by the Survo Editor, a general text editor. During a Survo session the editor calls Survo modules automatically according to the user's activations. The user has no need to know how the programs are linked together. He/she sees Survo as one integrated environment. Currently Survo includes over 100 C programs (.EXE files) and hundreds of other system files. All these files are located in one directory <Survo> and in its subdirectories. Typically <Survo>=C:\PROGRA~1\SURVO. The originator and main author of Survo is prof. Seppo Mustonen, PhD.
