I don't think it's particularly clever, but it works for me!

comment file1 and file2 are to be merged into file3
comment file 3 may or may not exist. Usual caveats about file structure, etc
comment matching across all three files
file3;acc=append
setjcw cierror=0
continue
listf file3
if  cierror=0 then
    comment file3 exists already
    fcopy from=file1;to=*file3
else
    comment file3 does not exist, need to use ;NEW on theFCOPY commanbd
    fcopy from=file1;to=*file3;new
endif
fcopy from=file2;to=*file3
