The complaint is not valid.  Borland and Microsoft compilers return FLOAT
values from functions differently.  Easy Language programs use the Microsoft
method.  DLL functions compiled with a Microsoft compiler can return FLOAT
values to Easy Language programs.  There is no problem returning FLOAT
values via pointers in a DLL function parameter list using either compiler. 
Furthermore, there is no problem using either compiler in passing pointers
to Easy Language FLOAT variables as DLL function arguments.

Bob,

Did you find that in the Tradstation manual or the Easy Language manual?  :>)
