Don't use tc.locate, it can be tediously slow because it's a sequential 
read. Use a unique index or primary key and do a tc.qlocate for an 
instant retrieval. I gave up using queries back in '98 because my files 
were large and queries took forever.

e.g
if not tcct1.open then errorshow() return end if
tf not tcct2.open then errorshow() tcct1.close() return end if
if not tcct1.edit then errorshow() tcct1.close() tcct2.close() return endif
tc.ct2.home()
tcct1.switchindex(MainID)
while not tcct2.eot()
    if tcct1.qlocate(tcct2."Mainid" then
       if tcct1.lockrecord() then
          --- Update tcct1
       else
          --- Error
       end if
    else
       if tcct1.insertrecord() then
          --- Fill tcct1
       else
          --- Error
       end if
    end if
    if Error then
       tcct1.canceledit()
       --- show error
       quitloop
    else
       tcct1.unlockrecord()
       tcct2.nextrecord()
    end if
end while
tcct1.close()
tcct2.close()
