Adriano,
could you check also inheritance in classes in FBApi
Is this ok that base class have function implemented?
In child class this function is redeclared as virtual; abstract
I suppose that this should be in reverse order
In base class function as virtual; abstract and in child implemented
but I see what hapened
Whe should decide about buffer alignment
I can use packed record instead of record then data are as is
But what is your buffer alignment when you fill data in that record?
Search for type_alignments:

Yes, message buffer contains null indicator for each value, including those
which are
not nullable.

Alignments in the buffer are irregular, you can't get it right with
these options. You
have to use packed record and byte arrays as fillers.

Hi,
but how to work with this?
After re-reading docs
http://docwiki.embarcadero.com/RADStudio/XE6/en/Internal_Data_Formats#Record_Types
i'd say you should not use nor special(explicit) alignment nor packed
records. Just ensure you have {$A+} when record type is declared and
you use record members with data types of

If you use {$A+} all fields should appear to aligned to 8 byte boundaries
(The default).
I think would be easier to make it controllable, to use packed record and
add some Foo Bar padding variables if needed.
If the original structure is continuous then packed record with correct
field sizes
virtual; abstract; methods in Impl classes hides concrete
implementation from non-impl classes.
Concrete implementations calls the virtual methods.
This way we can have standard classes and you can override the real
methods, not ones with fake names.

Ok if this is as designed then ok

Hi Alex,
I made full restore of tpcc.fbk with loging of each compresion request.
Result is here:

Record size is original length of request for compresion.
New RLE is RLE that I was developed for FB3, but was rejected.
