4D_Pack Introduction

Home

4D Pack v15.1

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 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.

Beginning with 4D v14 (Windows) and 4D v14 R5 (OS X), the 4D Pack plug-in is also provided in a 64-bit version. This way you can take advantage of the 64-bit architecture in a configuration using the 64-bit Windows version of 4D Server or the 64-bit version of 4D Server for OS X. The 64-bit version is included in the plug-in bundle. No specific installation is required.

Compatibility note: The _o_AP Save BMP 8 bits command is not supported in the 64-bit version of 4D Pack for OS X.
