Cosmac Assembler provides syntax highlighting and autocompletion for the RCA Cosmac 1802.

Language Support

Note that there are (at least) two different Cosmac assembler syntaxes. This extension supports:

• Comments initiated by "..".
• The DC mnemonic rather than DB.
• A.0() and A.1() to specify the high or low byte of a 16-bit address, versus LOW and HIGH.

Static completions are supported, but no dynamic completions at this point.
