## `register` -- remove the memory limit of the demo version

#### Introduction

`register(`Name, Key`)` registers the MuPAD installation on UNIX platforms.

#### Call(s)

`register(Name, Key)`

#### Parameters

`Name` | - | the name entry of the registration code: a string
`Key` | - | the registration key: a string

#### Returns

`TRUE` if the registration was successful, and otherwise `FALSE`.

#### Further Documentation

See the MuPAD license agreement, which can be obtained from http://www.sciface.com/mupad_download/reg_form.html`http://www.sciface.com/mupad_download/reg_form.html`.

#### Details

- The free MuPAD versions that you can download from the web have a built-in memory limit of 6 megabytes. `register` removes this memory limit on UNIX platforms.

  On Windows platforms, you can register your MuPAD version via the item ``Register'' of the ``Help'' menu.

  On Macintosh platforms, choose ``About MuPAD'' in the Apple menu and then ``Register''.

- You obtain a registration key via the following web page:

- http://www.sciface.com/mupad_download/reg_form.html`http://www.sciface.com/mupad_download/reg_form.html`

- You need write access to the directory tree where MuPAD was installed in order to register. If unsure, register as user root. Cf. example 3.

#### Example 1

If the key is correct and the registration was successful, `register` returns `TRUE`:

    >> register("My name", "12345-67890-ABCDE")

          Memory limitation removed.

                                       TRUE

#### Example 2

If you enter an invalid key, you will get the following message:

    >> register("My name", "invalid key")

          Wrong password or not registered user.

                                       FALSE

#### Example 3

If the key is correct, but you have no write permission to the directory tree where MuPAD was installed, the following happens:

    >> register("My name", "12345-67890-ABCDE")

          Cannot remove memory limitation.

                                       FALSE
