There are installation instructions on the site "Installation Instructions" by Ian M. Anderson and Charles G. Torre (usu.edu)

Failing that contact them the support link is in the left hand column.

Upload a worksheet or document. That command is useless on it's own.

@Rouben Rostamian  Very good. Maybe it is one of those situations where one needs to know the the format. Well I shall keep in mind your approach. It is simple.

@C_R It worked for me last night. Try removing the  `  ` from around the gamma. Also I have the Typesetting package loaded. 

Edit you brackets might be incorrect try this.

typeset(Typeset(`gamma2`),"\n" )

@acer I did not know or think of you combination of   typeset(Typeset(thename),"\n").That is nice and simple. I only have bits and pieces of data ( vague knowledge). I was only using the Typesetting pagkage to try and get around my problem. 

@C_R  Very interesting. I will experiment with that. I actually have some symbols for vectors setup that I copy paste in the 2D math format into the 1D

@acer The basic problem is I called the assignment name gamma2 :=<2|3|1> (a projective point). I can just change the name to gamma02. So then I can use typeset( gamma2,"\n") to get the nice symbol as I would usually do.

@C_R That works. Can you refere me to some help on this? Searching for  mo and mover don't seem to find much.

@C_R gamma2 is in projective coordinates. Pgamma2 is conversion to Cartesian coordinates for plotting. I admit I could change gamma2 to gamma02, so using typeset(gamma2) would work.

@dharr Thank you. It worked once I also added the that to the Dual Document Propetties as well as the hyperlink.

@C_R Yes, Have tried switching the worksheet tab. The biggese irritation with these "new" hangs, is when quitting Maple it often does not offer the option to save your work. It used too. 

@nm Oh I use Maple every night. I have it happen when editing something small.

@acer  @Carl Love Both great contributions. The example I put up at the start was made up on the spot. Sqr and it's beloved alias XX was random. CircleParmUHG and eparm are genuine.
I picked  alias because that is all I knew about

The export suggestion. works very well. Part of the problem is, I have been tring to follow a naming convention in a set of lectrues. But over the past two years have come up with more extensive procedures placed in the top level package or give them different names. e.g. I have a command LPproj  which 1) converts a  list of Cartesian points to projective points, 2) joins two projective point to make a projective line vector, 3) meet of two line vectors to make a projective point, 4) checks if line and point are coincident, 5) converts a list of projective points back to Cartesian points 5) converts a list of line vectors to a*x +b*y +c and 6) converts a*x +b*y +c to <a,b,c> line vector.  I had an old command in the UHG module that did 2) and 3). That is used in quite a lot of my old documents.

Using export JFunction:=LPproj in the UHG module neatly handles having to convert all those old documents when I open them again.

@acer Opps...sorry about that. Interesting on alias not having to load the sub package. Is that just because the module is defined in the worksheet.? When I try this in the actual package i.e. with(RationalTrigonometry) the alias-es are not woking. 

If I can't get it working later, could you take a look? I would just inclued a couple of the simple commands in it. 

@acer @Carl Love Thank you for the answers. What would produce a FAIL as opposed to false? I don't think it will cause me a problem. I don't think speed/efficiency is super important here. It is part of a couple of plotting commands I use to make diagrams and that involves a lot of back and forth fiddling to get them to look ok. The check for the 1 is to draw the perpendicularity symbols between the lines and points.  e.g
