Thanks for your reply.

You're right, there's no passphrase request with

| d:\gpg>gpg.exe --batch --homedir "d:\gpgdat" --no-auto-key-locate --no-default-keyring --keyring "d:\gpgdat\pubring.kbx" --delete-secret-and-public-key "66C040ADBE2C5728022F81DCCE09E0556C2C8CE0"

But that way a 'Pinentry' window opens, which I have to avoid:

| Do you really want to permanently delete the
| OpenPGP secret key:
| "John Doe <doej at example.com>"
| 2048-bit RSA key, ID 6C2C8CE0,
| created 2016-04-23.
| ?
| 
|                [ Delete key ] [     No     ]

followed by

| Do you really want to permanently delete the
| OpenPGP secret subkey key:
| "John Doe <doej at example.com>"
| 2048-bit RSA key, ID 174B70A0,

Kind regards
