1 - I want to buy PBDOS, but 2 - only if I can list files in directories with it 8-)

[Wayne Diamond]

1 - I want to buy PBDOS, the new price @ US$99 is appealling. After submitting payment details etc to the credit card server, can I download PBDOS straight away? I only want electronic docs, not printed, and im assuming it would be a relatively tiny download
2 - Im only buying it for one purpose and that involves being able to enumerate all files in all directories, i searched and searched through the PBDOS forum but couldnt find anything. Its a walk in the park to do it in Windows with FindFirstFile, FindNextFile, etc, but obviously I cant use Windows APIs in DOS, so does anyone have any code to do that? basically an implementation of "dir" (the simpler the better)
3 - obviously DOS programs cant see files in NTFS partitions, but can they see FAT16/FAT32 ? (its been so long since i used dos)

Thanks!
Wayne

1. All orders need to go through the Sales Dept. and are subject to regular business
hours (10am-6pm Eastern). Electronic orders are generally processed in a few hours.
The PB/DOS download size is about 3.4 Mb.

2. DIR$ works fine. There are also DOS interrupt calls that work very much like the
Windows FindFirstFile APIs. The FINDFILE.BAS example that comes with PB/DOS shows
how to go through all files in all directories. You can download the PB/DOS example
files here: http://www.powerbasic.com/files/pub/pbdos/

3. The type of partition doesn't make any difference to file scanning. DIR$ only sees
short filespecs though. If you need support for long filespecs, you'd need to go with
a particular set of DOS interrupt calls. This is not particularly difficult.

Tom:
I wasn't aware that there was a DOS interrupt to get windows LFN.
Got an example handy?
Cheers

If you can get a copy of FF.exe (the file-find utility from earlier versions of Norton Utilities) it will be hard to beat. I SHELL to FF.exe in PBDOS programs to catalog all files on an entire drive & write this info to a text file for subsequent processing. FF.exe is very fast and very small in size. I do not think that it would be hard to emulate in pure PB code, but that's another matter.

P.S. If any program written in PBCC, PBDLL or VB is any leaner & meaner than the FF.exe-PBDOS combination, I'll be amazed.

Cheers Tom, I'm sold. Hopefully the recursive crap has been done for me. <grin> Now don't leave the office until you get my registration!, Im hammering it in now

Thanks again,
Wayne

PS. Emil, ff.exe is indeed very fast but I don't want to include any 3rd party apps in this, I just want my exe in all its standalone glory

License received, thankyou - fifteen minutes isn't too long to wait I guess
Im cooking with gas now, and having some crazy flashbacks of old turbobasic/turbopascal days ...

Mel-- DOS provides extended file functions with LFN support, but only in DOS boxes
running under Windows. I don't have the details handy, but you can look them up
here. In the Docs section of the Downloads area, the Ralf Brown interrupt list has
the details. I believe there are several examples or libraries available for LFN
support in the PB/DOS section of the Downloads area. And, searching the Source Code
forum should turn up at least one example for a PB/DOS "CD" (change dir) utility
that does LFNs.

Wayne-- enjoy!
