ok, i managed to print two entries on the same screen.  thank heavens.
that restriction would've been enough to kill cdk's usefulness.

a couple of questions about the library:

1. is there documentation anywhere (other than source code examples)?

2. in entry_ex.c, there's a function:

   int XXXCB (EObjectType cdktype, void *object, void *clientData, chtype key)
   {
           return 1;
   }

  what purpose does this function serve?  i can't figure this out from
  looking at the source code.

3. we declare a variable of type CDKENTRY with a call like:

   directory1 = newCDKEntry (cdkscreen, 0, 0, title1, label1, A_NORMAL,
      '.', vMIXED, 40, 0, 256, TRUE, FALSE);

   then the source code calls:

   bindCDKObject (vENTRY, directory1, '?', XXXCB, NULL);

   what does this 2nd function do?  it looks like we've already declared
   directory1 to be of type CDKENTRY and assigned it to a CDKEntry
   object using newCDKEntry.   what does bindCDKObject do?

thanks for the help!  it's challanging learning all this from source.
the source takes me so far, but i need a little help to get up to snuff.
