It contains commands executed at startup and your command augmenting the library search could be one of them. I only have release 6.1 but I don't think it has changed enormously. The help pages say the following: --------------------------------------------------------------- Any number of statements may be placed in the initialization files and their effect is just like statements entered in a normal Maple session. Once all the statements in the initialization files are executed, the prompt appears and the Maple session begins. It is recommended that all statements in the initialization files terminate with a full colon (:) rather than a semicolon, to prevent any display. * Under UNIX, if there is a system-wide Maple initialization file with the name init under the src subdirectory of the Maple library, then this file is read and the Maple statements in it executed before the session starts (unless -s is specified). If there is a Maple initialization file named .mapleinit in the user's home directory under UNIX, this file is read next. * Under Windows based systems, the Maple initialization file is called maple.ini. It is searched for in the Maple 6/bin directory, and in the user's current directory. If one is not found in the current working directory, then the Maple 6/users directory is searched and, in multi-user environments, the user's personal profile directory. * Under Power Macintosh systems, the Maple initialization file is called MapleInit. It is read from the System Preferences folder and from the user:init folder. In multi-user environments, the file is also read from the user's personal profile folder (user:username). Additional initialization files can be specified explicitly using the -i option as described earlier. ---------------------------------------------------------- See help under command line options or startup. Hope it helps Stan -=*=-=*=-=*=-=*=-=*=-=*=-=*=-=*=-=*=-=*=-=*=-=*=-=*=-=*=-=*=-=*=-=*=-=*=-=*=- Date: Tue, 10 Oct 2000 16:14:21 +0100 From: "Dr Francis J. Wright" To: Subject: Problem with LIBNAME Put the above statement in your Maple initialization file. Irritatingly, the name and location of this file seems to vary with platform and release, but I think calling it maple.ini and putting it in the root of the Maple installation tree will work for your combination. To be precise, I have this file E:\Program Files\Maple V Release 5.1\maple.ini If that doesn't work then there are supposed to be various other places that Maple looks, which probably include the current directory. At one time, I think I had it in the bin.wnt directory. If you are sufficiently persistent then you should be able to find a directory where both you and Maple can find it! This is documented in the online help. Executing ?initialization should take you to the right page. (However, it is a moot point what current directory actually means in the context of MS Windows!)

Backhouse" To: Subject: Problem with LIBNAME Daniel, My simplistic solution is to have a worksheet for each library. The first line adds the library name to the list. A second line might load a package. No doubt there are better ways.

Note: maple.ini is NOT the same as maplev5.ini, which is a Windows initialization file. The file maple.ini contains only Maple commands, and if you haven't created one yet you probably won't have one. Produce it with any text editor (e.g. Notepad or Wordpad), being sure to save it as text rather than any fancy format such as rtf, and put it either in the folder that is current when you start Maple, or in Maple's bin.wnt folder.

For NT/Windows it is an ascii file "maple.ini". It goes in the lib subdirectory. Probably you don't have one. Create an ascii file with the single line: libname := "c:/mylib2",libname: Note that it is permissible to use forward slashes in the pathname, Maple will translate them accordingly.

It will be executed any time you start Maple. If you don't want to see the above statement shown when you start Maple, change ; to : at the end of the above line. maple.ini will be your initialization file. You can put more lines of code there, of course, if you need them.

Then every time you start Maple the file maple.ini will be executed. Be sure to put maple.ini into the directory where wmaple.exe is. For more see ?initialization .

It should contain files like maple.hdb, maple.lib, and maple.ind, which you must leave undisturbed. Create a new plain text file there called maple.ini. You can use the MS Windows accessory Notepad to do this. It should contain the following lines. libname := `c:/Program Files/Maple V Release 5.1/Lib`, `c:/.../mylib2`: savelibname := `c:/.../mylib2`: '...' should be whatever is the correct path on your computer. You can also add any other commands that you want Maple to execute at the start of every run. The libname command is what you asked for, but the savelibname command makes sure that your new procedures are saved in your library rather than Maple's. In Maple 6 you do much the same, creating a new file maple.ini in the ...\Users subdirectory. Adding lines to maple6.ini (which is in the same subdirectory) does not work.

If the file maple.ini exists in c:\program files\maple v release 51.\lib then add the line libname:=libname,`C:\\mylib2`: to it. If the file maple.ini does not exist, create a text file, put libname:=libname,`C:\\mylib2`: in it, save it as maple.ini, and put the file in c:\program files\maple v release 51.\lib.
