High Quality Content by WIKIPEDIA articles! Turbo Assembler (TASM) is an assembler package developed by Borland which runs on and produces code for 16- or 32-bit x86 MS-DOS or Microsoft Windows. It can be used with Borland`s high-level language compilers, such as Turbo Pascal, Turbo Basic and Turbo C. The Turbo Assembler package is bundled with the Turbo Linker, and is interoperable with the Turbo Debugger. TASM can assemble MASM source using its MASM mode and has an ideal mode with a few enhancements. Object-oriented programming has been supported since version 3.0. The last version of Turbo Assembler was 5.0, with files dated 1996 and patches up to 2002; it was supplied with Delphi and C++Builder for some time.
