We have a Visual C (version 6) DLL developed in Microsoft Host Integration Server 2000 WinRUI API to open/close mainframe LU sessions and send/receive mainframe data. We want you to convert the code to use WinSLI API instead of WinRUI.
The main C code file contains 2,000 lines of code. The DLL was developed in 1997. The DLL is used by a VB6 application.
