Re: [MI400] Field list in Query object

["Carsten Flensburg" <flensburg@xxxxxxxxxx>]

Hello Bobby,

I think you're on the right track - but the header is only 16 bytes: The 2
bytes preceeding the field name is the file id. The field name is followed
by a 2 byte select sequence number, again followed by a 2 byte sort priority
number.

The select field template size found in the header includes the 16 byte
header - so to calculate the number of fields you'd say (template size - 16)
/ 32

Best regards,
Carsten Flensburg
