So you want to develop Xtra only for own use or for sale ?
I think I can simplify your life :-) your task can be easy resolved IF
I little improve V4MD extending its ability to work with MemBuffer and BLOB. In particular I will add functions like:
BLOB.WriteBLOBData( gCursor, pMemBuffer )
where pMemBuffer is long number -- pointer to RAM buffer.
Now you can easy develop YOUR OWN Xtra which will build this RAM buffer and returns its pointer as long value. You see ?
I have implement this way already in VXCMD. Was going add it to V4MD.
What you think ?
