Raul, I'm a great fan of "start over". This is when I discovered there were ghosts in the closet! Starting over does not rid you of the images that you just created. They will pop up when you run another script.
The exciting thing about the beta version is that you can create inages in JHS as part of a dialog. You create the image as you would using viewmat in jqt. However, now it does not appear in a little wrapper that you can copy and paste in paint. Then you save it as a jpg and it is understood in the "real world" It is ready to be pasted in a Word document. In paint, one of the issues is that you must get rid of the image before you can use it to process another image, similar to the ghosts I am describing. Now, however, in JHS, the image acts just like a regular terminal in regard to images. A=:3 4$i.12 creates a table. With a color palette of colors, like crayons you can make an image. It appears without the wrapper. It is 3 rows of 4 columns of color. It appears right under the table of data. This is great. You can create one image after another happily. The trouble comes when you capture the sequence in a script. ( or two scripts). Once you use the first one, it seems to remember some of the images. Now it uses then in the next script with the wrong data array. As a side feature, it is creating a png for each image which is landing in the temp folder. Now I tried removing all those images and started over again. However, the old images persist. That’s when I went for: erase 'A' and got a 1. I was happy. However when I ran the bad script again the images were still mixed up. Thus my concern with the fact that a second use of (erase 'A') and it seemed strange to get another 1. In all the years I have known that there are many verbs defined in locales. It has never occurred to me that I might want to erase them. However, ie I use "each" I sometimes erase it from my active terminal, but that is about it for using erase. It has always seemed odd to me, but it worked well enough for data arrays so I could live with it. I guess that about sums up the answer to your "why question" My earlier post were in the beta forum but somehow this got into the programming forum.

Usually when I want a clean slate, I start J over again. This way, if I need something, that I forgot to put in the script, I can pull it out of the old J. And then I can shut it down when myi. tests are working well enough. This works better with jqt than with jhs. And you are right - I doubt many children would find interesting most of the things I play with. Actually, that's probably true of most people.
