Don,
The External Function capability will be in MetaStock for Windows 7.0 EOD as
well. I sure hope the 1% is a bad estimate on the part of Steve.

Don,
Less than 1 % will be using the new 7.0 and that's a very generous
estimation.

> * exports DLL functions by name
> * supports the stdcall stack frame convention
> * creates 32-bit DLLs for Windows 95, Windows 98, or Windows NT
> version 4.0 or greater
> This type of DLL is commonly called a Win32 DLL.
>
> Note: Microsoft Visual Basic does not have the capability to produce a
Win32
> DLL. Therefore, MSX DLLs cannot be written in Microsoft Visual Basic. A
> good alternative for VB programmers is PowerBASIC, an inexpensive compiled
> Basic that is syntax-compatible with VB and can produce Win32 DLLs.
> MSX DLL Capabilities
> The functions that can be implemented in MSX DLLs are similar in behavior
to
> the Standard built-in MetaStock functions. In other words, MSX Functions
> can be written to perform calculations based on any available price data
or
> results of other functions. All MSX DLL functions return a data array.
> This exactly parallels the behavior of the MetaStock built-in functions.
> The returned data array can be plotted by Custom Indicators or used in any

> MSX DLLs can perform calculations of virtually unlimited complexity. You
> have the full power of conventional programming languages like C or Pascal
> with all of their logic, data manipulation and rich flow-control
> capabilities.
> Things that you can do with an MSX DLL include:
> * Implement functions not provided with MetaStock.
> * Perform complex calculations on price data.
> * Provide multiple functions in a single MSX DLL.
> * Access stored MetaStock price data using MSFL (included in the
> MetaStock Developers Kit - see the MSFL documentation for details).
> * Create functions that can be used by Custom Indicators, System
> Tests, Explorations, and Experts.
> * Distribute your compiled MSX DLL to other users.
>
> Things that you cannot do with an MSX DLL include:
> * GUI functions including plotting and user dialogs.
> * Access the standard MetaStock built-in functions from within your
> DLL.
