FORTRAN is written for students who have no prior knowledge of computers or programming. The book aims to teach students how to program using the FORTRAN language. The publication first elaborates on an introduction to computers and programming, introduction to FORTRAN, and calculations and the READ statement. Discussions focus on flow charts, rounding numbers, strings, executing the program, the WRITE and FORMAT statements, performing an addition, input and output devices, and algorithms. The text then takes a look at functions and the IF statement and the DO Loop, the IF-THEN-ELSE and the WHILE loop, including applications of the DO loop, the LOGICAL declaration statement, library functions, other applications of the IF statement, and writing REAL constants in exponential form. The manuscript ponders on subscripted variables, the DATA statement, and the implied DO loop, doubly subscripted variables and matrix multiplication, input/output, and functions, subprograms, and subroutines. Topics include statement functions, subprograms calling other subprograms, reading using X format, control characters, reading using F format, INTEGER subscripted variables, and matrix multiplication. The publication is a dependable source of data for computer programmers and students interested in the FORTRAN language.
