## QED box symbol at end of proof location when typesetting

Hello

Thanks for any help that you may offer:

How does one control the location and appearance of the end of proof (QED) box when the document typesets?

In mine, it almost always appears on a new line or over the page and wastes lots of space.

I want it to the right-hand side and on the same last line as the end of the proof if possible.

Any assistance would be appreciated.

### The amsthm package can be

The amsthm package can be looked at for this.  The proof environment is defined by amsthm.  To avoid a LaTeX error since proof is usually defined in the document preamble see https://www.mackichan.com/techtalk/630.htm.

### This does not appear in the

This does not appear in the Typeset -> Options and Packages menu because it is not one of the built-in packages.

If you want to carry on using the proprietary TrueTex system that comes with SW5.5, it might work with the ntheorem package which will need to downloaded

https://www.ctan.org/pkg/ntheorem

and installed into the appropriate locations within the TCITex directory. This is not something I have tried personally but it might work. In any case, you can have a look at the package documentation to see if it does what you want.

What I did some years ago was to install MikTeX (available for free) and set SW5.5 up as front end per the instructions given on the following web page:

http://home.datacomm.ch/paulsoderlind/Software/Software.html

It involves some reconfiguration of SW5.5 but is well worth the effort. MikTeX comes with a comprehensive package library which, I think, already includes ntheorem. Otherwise, once set up, MikTeX will install any missing packages needed to compile a particular document on the fly either automatically or after asking for permission.

Whichever setup is used, you will need to add

\usepackage[...]{ntheorem}

to the document preamble where the brackets [...] contain the options for the ntheorem package.

I hope this helps.

Hi there

I have finished my thesis using SWP5.5 and other LaTeX editors to achieve compatibility with modern packages.

Now that the pressure is off, I still want to use SWP as an editor but with MikTeX supporting the packages.

I dutifully followed instructions given here: http://home.datacomm.ch/paulsoderlind/Software/Software.html

I can produce a Yap dvi but not a pdf. The error is "Error running Tex, pdf file not created" and indeed there is no update to my pdf.

Thanks

### The ntheorem latex package

The ntheorem latex package solved this problem for me. It works with SW5.5 + MikTeX. I haven't tried using it with SW6.

### Hi there. Many thanks. I

Hi there. Many thanks.

I can't find that package in Typeset, Options and Packages, Add Packages.

Is there a way of getting it?

Thanks again

### The packages on the Add list

The packages on the Add list are managed via a file that lists available packages for use with each document class.

Arbitrary packages can be added via Go Native.  See the Go Native section at https://www.mackichan.com/techtalk/455.htm
