System Libraries

Natural provides (sub)programs and data areas that are known to the runtime, but not included in your sources (e.g. user exits, RPC stuff etc.).

NatLS does not know about these modules, because they’re not part of your source repository.

To resolve this issue, you can create a folder called include in your root directory, next to your Natural-Libraries. Inside that folder you can create folders for libraries that were not part of your repository.

Example

Lets say you have the libraries LIBONE and LIBTWO and LIBONE wants to use RPC features. Your repository will look like this:

.natural
Natural-Libraries/
   LIBONE
   LIBTWO

According to the .natural file, your LIBONE library has SYSRPC as a step lib and you can’t resolve a LDA called RPCL within LIBONE.

To let your programs know about RPCL, you can create an include directory in the root directory of the repository and put the libraries and their files inside it.

Your repository will now look like this:

.natural
include/
   SYSRPC/
       SRC/
           RPCL.NSL
Natural-Libraries/
   LIBONE
   LIBTWO

Now the sources in LIBONE can resolve the LDA RPCL.
