Steve:
Yes, the offsets of the keys in the record are relative to zero. Also, remember that keys are not the same thing as fields. A key may span more than one field.
You don't need to reserve any extra space in your record for the key data. When you create the key, you tell Comet where in the record the key data is located. When you do a WRITE, you no longer need to specify KEY= . When you opened the file you indicated which key you wanted to use (the primary or a specific secondary key). When you do the WRITE, Comet looks in the record buffer at the position for the key in use (the one specified at OPEN) and copies it for use in accessing the key tree.
