 What about Directory Freedom 
 ?
 It is small, fast and now open source.
 There is also File Maven for DOS .
 It is small, fast and free but not open source.

Re: [Freedos-devel] ideas about FreeDOS resident calculator

[Tony G]

I still think it would still be easier to build a calculator API and just 
implement what you need into Blocek. Simple calculations would be of course 
easy to do, but imagine having to do complex functions, with nested levels 
would require recursive calls on an interrupt...

The original intent of interrupt handlers of course are to perform quick 
tasks and return to the caller, so that would rule out the interrupt theory. 
However, I am not without a suggestion. FDRC can use an Interrupt to give an 
address to a function lookup table in ES:BX DX:AX whatever. Each of the 
mathematical functions of FDRC can be offset from that table...

The only problem would be the return issue, perhaps pass a pointer in 
another register pair or push a pointer on the stack.

Maybe conversions from/to another number representation systems.
255dec = FFh = b

Re: [Freedos-devel] File manager

[Alain M.]

There is  one Real Mode NDN, it is amall and much faster...

No LFN, small footprint, works very well :)

if you don't find it anywhere, I have a stripped down version (I lost 
the full distro)

I am searched for a small and fast open-source file manager, but
found nothing. Now I use Volkov Commander, but it is not open-source
program :-(

IMHO, NDN is very slow and have many useless (for me) features.

Yes, I agree with you. Two functions are obvious (calculating the value
of math expression, and checking for presence of another copy of FDRC
in memory). Which functions should be available via INT 2f except
these?
