my code is pretty small... it should easily fit the attachment limitations of 
this list :)

i still have a few more tweaks to add to it as a few things are still specific 
to certain types of messages but overall, it is pretty straight forward ;)

that is/was my thinking as well...

yes, part of what i'm running into is platform dependency problems... i forget 
which unit it is that's triggering the platform stuff but where it is failing is 
when trying to bring in platform stuff like loading libraries and there's 
nothing in my code that needs any libraries to be loaded for any reason that i'm 
aware of... it is possible that "WalkParts" might want something loaded from a 
lib but i do not need anything like that for my immediate purposes since i'm 
only looking for the text/plain section(s) and extracting them to an ASCII text 
file...

i shall try to grab these in the future... one thing that may also be causing 
waves is that my OS/2 and DOS FPCs are 2.4.2 releases whereas on my development 
machine(s), i'm pulling FPC and lazarus from their SVNs and building them from 
the ground up... both of my development machines started with nothing on them 
until i pulled the code from SVN and the bootstrap compiler to kick it in the 
arse and build working environments...

yeah, the above failed miserably... i didn't realize that LFNs were necessary 
and the DOS version on OS/2 simply cannot access OS/2 LFNs in any way shape or 
fashion at all...

OS/2 straight? not the OS/2 w/ EMX?? it really doesn't matter to me as long as i 
end up with a working executable for the task at hand...

you are absolutely 100000000000+% correct on that... there's nothing visual... 
the tool is fired from a console command line... there's little to no output 
(unless i decide to add some for logging purposes)... and, lastly, the tool is 
doing nothing more than extracting a/the text/plain MIME section(s) from 
messages saved as text files... the only other thing the tool is doing is 
converting "characters" like the trademark symbol from their unicode(???) 
character back to the old DOS 8bit/7bit old school alternative... ie: the 
trademark symbol is located as the "= 9 9" (spaced to prevent conversion) MIME 
text in the message body and converted to "(tm)" which any old DOS 3.x can 
understand :)

let me fix up a few things and i'll post another message, in the list or 
privately, containing my current code... i'll also try to bang up the error 
messages from the attempts to compile to the OS/2 (native) target...

thanks for your interest and assistance!
