I have just about got a sub-release ready that will include support for it.
I'm finishing up some much needed improvements to the TIB_Ledger control.
This is actually a wonderful control that needs all its finishing touches...

Anyway, you will use an execute immediate call since there is an SQL
processing for this. Thus, it isn't actually done via the normal API calls
for transaction (though there may also be enhancements there too). There is
a new statement type called stSavepoint that I will use for this.

Please stay tuned for the next release or if you are in a hurry privately
request a patch and specify if you are a commercial or trustware user.

Kind regards,
