Good.

So are we just allowed to report bugs?

I couldn't resist to try a potential wasm/jwasm/uasm/asmc competitor:

missing features (so far):
- no ORG directive (so no device driver development possible?)
- SEGMENTs missing ( apparently ASM.COM is a "flat"-only assembler )
- no support for listings
- EQU exists, but no math possible ( "xxx EQU 1+1" is rejected )
- no END directive (important, since it allows "self-compiling" .BAT files)

bugs:
- LDS opcode rejects any type of operands that I was able to imagine
- math accepted for direct operands, but ignored ("mov ax,1+2" is assembled to "mov ax,0000")

---
MS-DOS forever!
