NetCOBOL tailors its behavior at runtime by checking the settings of a number of environment variables and runtime options. You can set these variables in a variety of ways, documented in the "NetCOBOL User's Guide".
Before starting to debug, it is a good idea to specify all the environment variables you require in the initialization file (COBOL85.CBR). To do this, either edit the file, or use the Runtime Environment Setup Tool. Settings to consider include:
File allocation mappings.
COBOL sub-program name to DLL file name mappings.
Other environment settings specific to your application requirements.
