Before microsoft there was very little scope
for personal computers and softwares related to those computers. Still there were some
softwares and software building programming languages. FORTRAN or formula translation,
the first high level programming language, was invented by John Backus for IBM, in 1954,
and released commercially, in 1957. It is still used today for programming scientific
and mathematical applications. Fortran began as a digital code interpreter for the IBM
701 and was originally named Speedcoding. John Backus wanted a programming language
closer to human language, which is the definition of a high level language.
At that time the softwares available were Aldus Pagemaker, Trillian, Wordstar, Computer
Chess, VisiCalc Spreadsheet. WordStar - The First Word Processor Released in 1979 by
Micropro International, WordStar was the first commercially successful word processing
software program produced for microcomputers and the best selling software program of
the early eighties. first desktop publishing program was created by Paul Brainard and a
company called Aldus, the program called "Aldus Pagemaker 1.0" was released in July,
1985 for the "Macintosh" and in December, 1986, for the "IBM". If you go with the
history of operating system than previously there was nothing except UNIX.
