Obscure DOS question

Append allows FCB-oriented file opens to "succeed"  if the append.exe TSR 
is loaded and you've mentioned the directory where the files actually live 
in an APPEND command line. You can't actually write more files than the 
file structure supports if APPEND is all the extra help you've got.

Some of my notes say that APPEND is incompatible with BACKUP. Presumably 
that's the DOS 3.3 version of BACKUP (and APPEND) since I'm reading printed 
DOS 3.3 docs here.
