From Chris Karwowski:
Assembler IDE is a lightweight developer studio that is aimed to make compiling assembly code easier by automating this process and integration with code editor and debugger. Assembler IDE provides debugging, code editing and compiling with NASM, TASM and FASM. The Assembler IDE is freeware. However, if you like my project, it would be nice if you've made a donation to keep me interested in further development. This version is the first release on CNET Download.com.
What's new in this version:
This version is the first release on CNET Download.com.
Simplicity. It's not overloaded with features and options. It features a basic editor and compile buttons (should have been called 'assemble' buttons though). You don't have to get burdened with what options you have to set and where. Type the code in and click a button. That simple. Lets you focus purely on learning the language.
Doesn't let you customize the editor. You can't change the font or anything for that matter. The author should at least make it use a mono spaced font by default.
