(Received 19 May 2000; accepted 8 June 2000)

We regret that we forgot that the program name CRUNCH (Langs et al., 2000 ) had been associated with the direct-methods work based on Karle–Hauptman determinants as described in the above letter by de Graaff & de Gelder (2000 ).

We have adopted the name CROQUE for future reference to our program.
