I don't know if this is what you are looking for, but the Communications
Toolbox already includes a routine that does this (which will be included
in System 7.0, and 6.0.x if you get the CommToolbox from APDA).

Some of the nice routines included are:
   AppendDITL(theDialog,theDITL,method);
   numItems = CountDITL(theDialog);
   ShortenDITL(theDialog,numberOfItems);

Also, the AppleTalk "Standard File" utilities NuLookup and NuPLookup are
also included.
