• supports binary, s-records or intel-hex output file formats.
• optionally generates debug information file.
• three segments (code, data, bss) for ROM-based programs.
• 'struct' keyword for easy declarations.
• instruction cycle count in listing.
• full conditional assembly.
• C-style expressions, accept base 2...36, using either %, $ and 0x prefixes or <base>#<value> format, 32-bit calculations.
• full macro capability.
• runs under MS-DOS 3.x+, Windows 9x, NT, 2000, XP and Linux x86.
