SjASMPlus от z00m

[Ped7g]

а tr-dos может больше чем одну букву?
правда я где то читал про 3-х буквенные расширения но подтверждения так и не видел

As far as I understand it (and how sjasmplus supports them), the 3-letter extension is total hack just leaking the one letter extension into the "file start address" field at offset 9 ... I don't think it does use any bit-7 mark, it's just the tools using the TRD use the other two bytes to display three letter extension.

This is the level of SW quality I don't want to deal with, so I just added the code to sjasmplus and I'm running away from anything TRD related...
