'Linking Data'

'Linking Data'

There is a new feature in 4C that allows linking of data between 4C applications on different servers and between 4C applications and external applications that have a DDE interface. I call this feauture LData (linking data).

In order to start using ldata, you need to: Currently, there are 3 ways to link data. An LData item has two parts. One is a definition in the s_ldatah file. The other is the runtime open with the sys.open_ldata() system pcl. For every rcd in s_ldatah you may have multiple sys.open_ldata() calls. Every sys.open_ldata() call refers to a single LData item. This will be a single data field in the 4C application and may be a single cell in a spredsheet. The fields defined in the s_ldatah file and how to use them follows. You will need to use xlfile to access this file for now. As soon as the final definition is done, the bootstraps will have some new programs for defining your LData.

Once you have defined an LData, you can use the links with 3 new system PCL's.
