Here's a problem I've been battling... any pointer would be
appreciated.

  What's the quickest way to concatenate one large file (~100K) to 
  another using Microsoft C under MS_DOS?  Write now I'm just opening 
  the two files and reading from one and append to the other, but it
  is rather slow.  The DOS "copy" command can do this much more 
  quickly using "copy A + B" but I can't figure out how to run
  "copy" from a C program.  I've tried calling "copy" with a 
  spawnl() command but that didn't work so i made a batch file
  that called copy and then tried to spawnl() the batch file,
  but that didn't work.  So, any suggestions? Any I overlooking
  something extremely obvious?

Thanks in advance,
