Re: modern reply.exe created using only batch

carlos wrote:@einstein1969: the base used is 16 with rle that uses [number] that means repetition of characters.


Hi Carlos,

Here you can see what I mean. It 's a starting point.

ANY2BAT BASE85

Hi to all, I started a bath to include any file in BAT, or other compatible with the chosen dictionary. This uses base85 characters that seem not to cause problems. (I'm no expert in this!) For compressed files the ratio of wasted space is quite low. I tested on GetInput.exe.cab 566 bytes and the ou...

Re: Drawing pixel resolution graphics in text mode

Hi Antonio, The work done with the font is gigantic and fantastic! I'm surprised your ability to synthesize and speed of execution. I, unfortunately I have not yet mastered what have you and go slow with color management. Now I'm working on the luminance and the distribution of pixels, an old job I ...

Re: slice.cmd

@einstein1969: skip less or equal to 0 fail. instead of this: set /A #=%b%-1 For /f "skip=%#% maybe some like this will work: set "skip=" if %b% gtr 1 set /A "skip=%b%-1" if defined skip set "skip=skip=%skip%" For /f "skip=%skip% Thanks, I see. now works. ein...

Re: slice.cmd

Hi Sponge Belly and Carlos, I have tested on 700kb about and there are about 7 seconds of delay. With a file of 1.2MB the time is about 20 seconds. For higher size the time increase exponentially. I have a 16Mb text file and the time is over five minutes. I have break before finish. This version is ...

Re: modern reply.exe created using only batch

why rle encoding? Using base encoding is much better einstein1969 Why is it better? Does it compress recurring bytes also? I'm sorry, I meant that a file already compressed (carlos uses makecab normally) if passed to another base (higher base is better) has less wasted space than using a low base +...

Read a file with WHITESPACE separators

Hi to all, Preamble: I'm really happy with the new development to write the files with any content. I'm working on compression algorithms in real time in dos batch for quite some time and I hope to churn out something with this piece. Recently I'm working on dithering and anti-aliasing and ray-traci...

Re: Create nul and all ascii characters with only batch

I saw that you are trying to create a binary file that contains the characters.

Why are you using the makecab?

Should not use what you have developed to create an ad hoc binary file?

Re: READ/WRITE binary files

thanks you very much carlos.

All that has been developed is very constructive. Writing fast track again via dos is now the target.
I'll try to throw something down even if I do not have much experience. Thanks again to you and to all.
