Using call-in support
VA Smalltalk Server provides call-in support for the most common high-level languages (HLLs). Supported HLLs are:
•COBOL
•C
Call-in support provides application developers with significant new capability to call Smalltalk applications from legacy HLL applications. HLL programs can now call host VA Smalltalk applications directly by using standard workstation inter-language calling conventions. This support provides several significant benefits:
Improved performance
You can use new HLL function calls to start and stop execution of an image without incurring the overhead of image initialization each time. This approach makes it possible to create efficient, long-running application scenarios.
Flexibility
You can call any class method in the Smalltalk image from an HLL program.
Efficient interaction
By using the supported call-in parameters, you can share data between the HLL application and the Smalltalk image.
