Introduction to the WinAsm Studio Assembler Integrated Development Environment

WinAsm Studio is a free Integrated Development Environment IDE for developing 32-bit Windows and 16-bit DOS programs using the Assembly language. The Microsoft Macro Assembler (MASM) is supported inherently, while FASM is supported by the FASM Add-In.


WinAsm Studio is optimized for size and speed, yet contains a number of useful features such as intellisense which will assist you in creating Windows API based programs. Highly extensible via user-created add-ins. Includes a powerful Visual Resource Editor.


WinAsm Studio is a front-end to MASM but does not contain any MASM file. MASM itself can be obtained via Hutch's MASM32 distribution.
