Smalltalk MT is an implementation of the
Smalltalk
Smalltalk is a purely object oriented programming language (OOP) that was originally created in the 1970s for educational use, specifically for constructionist learning, but later found use in business. It was created at Xerox PARC by Learni ...

A programming language is a system of notation for writing computer programs.
Programming languages are described in terms of their Syntax (programming languages), syntax (form) and semantics (computer science), semantics (meaning), usually def ...
created in 1994 by Tarik Kerroum to deal with some of the shortcomings of Smalltalk-80 style of implementations. Smalltalk MT adopts a different approach in that the Smalltalk source is

This allows the developer the freedom of working with compiled code without the need for the traditional compile-link-run cycle. This is like a specialized form of incremental or

Dynamic compilation is a process used by some programming language implementations to gain performance during program execution. Although the technique originated in Smalltalk,Peter L. Deutsch and Alan Schiffman. "Efficient Implementation of the S ...

Smalltalk MT directly interfaces to
DLLs in exactly the same manner as
C which allows DLL calls to be tested directly in a Workspace, which allows a scripting style of approach to accessing any DLL based code.
For example, one could write in a Workspace the following (single line or multiline, breaking on the '.' character) to reverse the string 'abc':
a := 'abc'. WINAPI _strrev: a. a inspect.
For 64-bit Windows,
try:
a:= 'abc'.
WINAPI _wcsrev: a.
a inspect.
The WINAPI call directly calls the DLL function _strrev natively passing parameters from the Smalltalk environment to the C environment and back.
Smalltalk MT has a close integration with COM objects and fully compiled COM components can be created that operate in exactly the same way as C/C++ COM objects.
In 1998 David Anderson teamed up with Tarik Kerroum to advance Smalltalk MT into the high performance and graphics areas.
