Hi:
 
    (I'm the Newbie).
 
    I determined that, altho I could finally compile the 90-odd libcurl .c
files, and then link them with my xHarbour language program (see
_www.xharbour.org_ (http://www.xharbour.org) and _www.xharbour.com_
(http://www.xharbour.com) and the ng comp.lang.xharbour), that the .c programs already
used in xHarbour low-level routines are strikingly different than those in
libcurl :((
 
    Such that, unfortunately, I have to creep off to my newbie cage, and
try to learn the native tIP classes that are part of xHarbour.
 
    Below is a short example of a .c program that is compiled and linked
into our RunTime Library (RTL). It is the module that transforms a numeric
vbl to a string with a set number of 'zeros' in front of it. I received no
encouragement whatsoever from the gurus in the xHarbour ng when I
suggested that we make libcurl a library for our own harbour language. They said
use our *own* tIP Classes.
 
So, thank you all ! (I'm way over my head here.)
