# How to load Maple package ??

I have downloaded second version of DGApplications to work with abstract Lie algebra. The file is actually .mla file and it is executale(as when we open it, a prompt ask, "do you want to execute this file"), but when I press ok for execution, a file open with command like as

what should I do after this, is it a some sort installation procedure. I keep all my Maple file in E drive with following path:

E:\Maple work\General Maple Workout

The help on this issue is also provided on the site as follow but I could go beyond libname:

(1) Create or identify a directory (folder) where you will keep the mla file(s) and the help file. Copy the mla and help files there.

(2) Open Maple, at the prompt type libname. This will display where maple currently looks for packages. You need to modify libname to include the path to the directory used in (1). This can be done by assigning libname := newpath, libname;.

(3) If you are installing the DifferentialGeometry package: Execute with(DifferentialGeometry) to load the package. At the prompt execute DGbuild; and verify that the build number matches the build displayed on this website. This step can be ignored if you are installing DGApplications.

(4) Step (2) can be automatically executed at the start of every Maple session by adding the libname assignment to your maple init file. In Maple Help, see worksheet,reference,initialization. Or go to the URL http://www.maplesoft.com/support/help/Maple/view.aspx?path=worksheet/reference/initialization .

• "march" is the Maple archive utility, so (unless you want to do some archive work) do not execute *.mla. Instead open it from within Maple. – GEdgar May 9 '16 at 20:33

I hope, this might work.

DGALib := "E:/Maple work/General Maple Workout/DGApplications.mla/";

libname := DGALib, libname:


libname := libname, "E:\\Maple work\\General Maple Workout\\DGApplications.mla":

• Sorry for the lateness of this reply. I don't know of such a video. Check to see if DGEnvironment is defined in your MLA library. You can see what is defined inside your MLA library with: LibraryTools:-ShowContents( "E:\\Maple work\\General Maple Workout\\MLA_Files\\DGApplications.mla"); – saforrest Aug 22 '16 at 9:15
