4D_Pack Introduction  


 

 

The 4D_Pack plug-in provides 4D developers with additional routines.

4D_Pack command names have the “AP” prefix in order to avoid any confusion with 4D commands. They also use the uppercase/lowercase convention depending on whether they are commands or functions.

Compatibility Note (4D Pack v16): 4D Pack routines have been progressively integrated into 4D itself, or removed gradually as they become obsolete or unnecessary. Today, the 4D Pack plug-in contains only a very small number of routines and will no longer evolve. Starting with version 16 of 4D Pack, all the routines of this plug-in are deprecated and their use is no longer recommended.

You install the 4D_Pack plug-in just like any 4D plug-in: you must put it in the Plugins folder located either next to the executable application or next to the structure file of the database. For more information, please refer to the Installing plugins or components section in the Design Reference manual.

The 4D Pack plug-in bundle contains both 32-bit and 64-bit versions of the product.

Due to changes in technology and continuous integration of new features 4D, 4D Pack commands have been removed from successive versions. This section lists the commands that were removed as well as their recommended alternatives.
