Turbo C

    Borland's C compiler for IBM PCs.

   Turbo C, version 1.0, was introduced by Borland in 1987.  It
   offered the first integrated edit-compile-run development
   environment for C on IBM PCs.  It ran in 384KB of memory.
   It allowed inline assembly, supported all memory models, and
   offered optimisations for speed, size, constant folding, and
   jump elimination.

   Version 1.5 shipped on five 360 KB diskettes of uncompressed
   files, and came with sample C programs, including a stripped
   down spreadsheet called mcalc.

   Turbo C 2.0 has a debugger, a fast assembler, and an extensive
   graphics library.

   Turbo C has been largely supplanted by Turbo C++, introduced
   circa September, 1990 for both MS-DOS and Microsoft
   Windows.
