Debugger command syntax

IBM® Informix® 4GL (I4GL) provides a program debugger. Genero Business Development Language provides a program debugger with a different set of commands as I4GL, compatible with the well-known gdb tool. This debugger can be used alone in command line mode, or with a graphical shell compatible with gdb, such as ddd:
ddd --debugger "fglrun -d myprog"
