NetCOBOL programs are designed to work well with Visual Basic. The main consideration in debugging these mixed language applications is in bringing up the two debugging environments. The COBOL subprograms are prepared exactly as if they were to be called from other COBOL programs.
Because the Visual Basic program will be calling COBOL, Visual Basic is brought up under the COBOL debugger. This ensures that calls from Visual Basic to COBOL can be intercepted by the COBOL debugger and the appropriate actions taken to let you see your COBOL source code.
When you are debugging mixed Visual Basic and COBOL applications you have two complex environments active. To ensure that they interact correctly it is important you follow the start-up and close-down steps documented in this chapter.
