This process was the cumbersome product of the extremely limited resources of the early IBM PC models. For example, the Microsoft Pascal system consisted of two compiler passes and a final linking pass (which could take minutes on systems with only floppy disks for secondary storage). They all made C compilers (and some made Pascal compilers), which all worked in a similar fashion. In the IBM PC market of the early 1980s, the major programmer tool vendors included IBM, Microsoft, and Lattice. This cycle was the result of limited computer power and small amounts of memory. Programmers wrote code in a text editor, a compiler created object code from source (often requiring multiple passes), and a linker combined object code with runtime libraries to produce an executable program.
Historically, the vast majority of programmers saw their work flow in terms of the edit/compile/link cycle, with separate tools dedicated to each task. Philippe Kahn first saw an opportunity for Borland, his newly formed software company, in the field of programming tools.
