At a minimum, Borland quickly supported win3.xxx either at the same time or close to 1992 with their OOP release. I remember being able to make both Turbo C and Turbo Pascal programs with a module. TheyBorland released a Win TPU UnitWin TPU Unit for their older Borland DOS releases.
In 1992 Borland released two versions named "Turbo Pascal for Windows" (TPW), for Windows 3.x: TPW 1.0, based on Turbo Pascal 6, and later TPW 1.5; they were succeeded by Borland Pascal 7, which had Windows support. The Windows compiler in Pascal 7 was titled 'Borland Pascal for Windows'.
Both versions built Windows-compatible programs, and featured a Windows-based IDE, as opposed to the DOS-based IDE in Turbo Pascal. The IDE and editor commands conformed to the Microsoft Windows user interface guidelines instead of the classic TP user interface.
I seem to remember Watcom C could also make Win16 programs but I don't member for sure.
The support for Windows programs required the ObjectWindows library, similar but not identical to that for the first release of Borland C++, and radically different from the earlier DOS Turbo Vision environment.
Turbo Pascal was superseded for the Windows platform by Delphi; the Delphi compiler can produce console programs in addition to GUI applications, so that the use of Turbo and Borland Pascal became unnecessary.
