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, Turbo C 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 latest version of Turbo Assembler is 5.0, with files dated 1996 and patches up to 2002; it is still supplied with Delphi and C++Builder.

Lazy Assembler[1] is a freeware assembler not associated with Borland which is compatible with TASM ideal mode but with support for newer instructions not supported by TASM: MMX, SSE, SSE2, SSE3 (PNI), SSE4 (MNI), 3DNow!Pro. It was last updated to version 0.56 on 6 August 2007; the website is no longer available, but the program is available for download.[2]
