Poor documentation, +1500 pages, are you kidding ?

You have no interest to invest your time into DLL coding, because the 64 kb
limit of TS4 will be removed with TS5, probably available in January (1999
assumed)

You do not have to use this.
The size of the circular buffer ( mainly used when dealing with arrays) is
managed by the TS_KIT.DLL.

These functions are global variables functions available in a special version
of the TS_KIT.DLL that has been available 5 years ago from Omega, but that is
not provided withthe later versions
This DLL is still available from my web site ( www.sirtrade.com).
I wrote an article in TS Express 5 years ago explaining how to use these
functions.

No.
The DLL's are compiled and linked with TS_KIT.H
They are specific to TradeStation.
You need a 16 bits C compiler to build them, like Borland 3.1
If you are not familiar with C, you will spend a lot of time to make them work
as expected.
Again, you have better to avoid DLL coding if your goal is to break the 64kb
barrier.
Better is to use a Global DLL product like Doug Deming (Investment
Engineering, see the links page from the sirtrade web) and use the
IncludeSystem TradeStation feature ( you can build bigger systems by linking
several 64kb systems).
