Should you encounter an error in the execution of your program, you can use the debugging facilities in AcuBench or ACUCOBOL-GT to investigate the problem. See section 1.7.2 and Chapter 3 of the ACUCOBOL-GT User's Guide for a detailed description of debugger options and use. Once the debugger is running, it may be helpful to use the "tf" option to turn on file tracing. Included in the file trace are all calls to esqllib.dll. To generate the most detailed level of file tracing, follow "tf" with the number "9".
