This manual investigates the fundamental syntax and operational mechanics of the FORTRAN IV programming language as implemented through the WATFOR and WATFIV compilers. Charles R. Bauer provides a structured, self-instructional framework designed to guide students and novice programmers through the logic of early high-level computing. By focusing on the specific diagnostic and execution capabilities of the WATFOR/WATFIV systems, the text establishes a clear methodology for writing, debugging, and executing code in an academic or research environment.

Experts recognize this manual as a foundational resource for understanding the historical development of compiler technology and early programming pedagogy. Readers frequently note the technical density of the prose, which serves as a precise reference for those working with legacy computing systems.
