Here are answers to some questions I have received about writing TS and SC
DLL's using PowerBasic and about some DLL source code and messages I posted:

I don't remember. I looked at that picture months ago and discarded it and
the address. Try OmegaList archives or write Mark Brown.

Check my recent DLL posts on the OmegaList and CodeList. They show
source code. Check Tim Tillson's web address also.

Check the TASC web site. They have EL code for T3. Also, Bob Fulks has
posted code for this on the OmegaList in the distant past.

The zero lag filter needs data from the future which is only available
if there are bars forward in historical data. Most MA's don't rely on future
data but they also don't have zero lag.

Yes. I have passed floats, longs and integers in both directions.
Float result of DLL math routines overlay on a chart perfectly with
the same math operation coded in EL.
