4D_Pack, Introduction
version 11 (Modified)
The 4D_Pack plug-in provides 4D developpers with useful additional routines.
The 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.
Installation
You install the 4D_Pack plug-in just as 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 Design Reference manual.
