This option is for LANSA's internal use and there is no reason for you to select it. To include it on this dialog, you must select/check the Show Advanced Compile Options in the LANSA Option's Compile tab.
The source code needs to be kept if the resulting objects are to be executed on a platform other than Microsoft Windows. It is also required in order to fully resolve dump files, though its possible to produce this when needed, provided the original Visual LANSA development environment is retained.
If the source code is being moved to another machine for subsequent (re)compilation, you must use this option.
The source code to be kept includes:
The table/index/view/OAM creation code if generating a table
The process/function/component creation code if generating a process, or function or component.
The corresponding define and make files.
