I just loaded the two portions into xLeap (loadamberprep, etc) and then 
used a pdb file containing info on both units to align them with each 
other (NCH = loadpdb) command and then just used "saveoff NCH NCH.lib". 
  I guess I should have used combine.
I've read the manual about combine and tried playing with xLeap since I 
got your reply and have some questions.
1.  Do I have to start over, or can I combine the two units within NCH 
now?
2.  If I have to start over, how can I use combine to combine them 
AFTER aligning them to each other (because, by this time they are part 
of a new unit defined in loadpdb)?  Do I make any bonds between them 
AFTER I combine them?
Thank you again for all your help.
