Hi Leigh, What I would suggest is to look at this site: http://www.jsoftware.com/jwiki/Grid/Class
That page has an example of a grid that will allow you to data. Specifically, try the topic "Display numeric matrix given the data name" which can be found here: http://www.jsoftware.com/jwiki/Grid/Class#head-05665bc9021837af50d87ac82 210d5219793ef67 Unfortunately, this sample code use the J object oriented frame work. It basically created the "myform" class which inherited it from the "jzgrid" class. So when running it, you can play around with the data but if you check the source CELLDATA_myform_ class property, the data was not being updated with your changes to the grid. One way to get the updated data is to use referencing. If you would read the myform class, there is a line there that says: gdemo_run=: 3 : 0 wd GDEMO grid=: '' conew 'jzgrid' show__grid 'celldata' wd 'pshow' ) What you should be interested in is the code where the grid_myform_ is initialize with a new instance of the jzgrid class: grid=: '' conew 'jzgrid' Actually the author of the page, I believe Rick Sherlock, is being helpful here by providing you with access to the inherited class. So to access the changed data or the actual grid data, you need to do the following: NB. Get a reference of the inherited jzgrid class gridInstance=: grid_myform_ NB. Inside the jzgrid class, there is the CellData property which actuall holds the grid data CellData__gridInstance 42 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 0 2 2 6 4 10 6 14 8 18 10 22 12 26 14 30 16 34 18 38 0 3 6 3 12 15 6 21 24 9 30 33 12 39 42 15 48 51 18 57 0 4 4 12 4 20 12 28 8 36 20 44 12 52 28 60 16 68 36 76 0 5 10 15 20 5 30 35 40 45 10 55 60 65 70 15 80 85 90 95 0 6 6 6 12 30 6 42 24 18 30 66 12 78 42 30 48 102 18 114 0 7 14 21 28 35 42 7 56 63 70 77 84 91 14 105 112 119 126 133 0 8 8 24 8 40 24 56 8 72 40 88 24 104 56 120 16 136 72 152 0 9 18 9 36 45 18 63 72 9 90 99 36 117 126 45 144 153 18 171 0 10 10 30 20 10 30 70 40 90 10 110 60 130 70 30 80 170 90 190 0 11 22 33 44 55 66 77 88 99 110 11 132 143 154 165 176 187 198 209 0 12 12 12 12 60 12 84 24 36 60 132 12 156 84 60 48 204 36 228 0 13 26 39 52 65 78 91 104 117 130 143 156 13 182 195 208 221 234 247 0 14 14 42 28 70 42 14 56 126 70 154 84 182 14 210 112 238 126 266 0 15 30 15 60 15 30 105 120 45 30 165 60 195 210 15 240 255 90 285 0 16 16 48 16 80 48 112 16 144 80 176 48 208 112 240 16 272 144 304 0 17 34 51 68 85 102 119 136 153 170 187 204 221 238 255 272 17 306 323 0 18 18 18 36 90 18 126 72 18 90 198 36 234 126 90 144 306 18 342 0 19 38 57 76 95 114 133 152 171 190 209 228 247 266 285 304 323 342 19 As you can see from the data above, I replaced the value at (0,0) to 42 in the displayed form with a grid. Also notice how I used underscores to access the referenced class. Another thing is that you may wonder how I know that CellData is a global property of the jzgrid class. Actually, when I started answering this question, I didn't really know. What I did was opened the Project Manager, went to the Library Tab and in the Select From list box, I highlighted jzgrid then selected the Tools->Global Assignments In File menu item. This gave me a rather long list of global names and selected CellData as the most likely candidate. :) Good luck and don't hesitate to ask question. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Leigh J.

Can someone write up some J code that allows a user to input data via a grid into J? For example, set mat equal to the values that someone puts into a 3x3 grid. Thanks.

The old User Manual was before my time but I suspect that the answer to your question is "no". I found the best solution for trying to understand grid, was to study examples of use. The demo gave me a good idea of available functionality and what some of the options did, but I found the way it is implemented obscured how to actually use the grid in an application. The best simple examples of using the Grid that I know of are on this wiki page: <http://www.jsoftware.com/jwiki/Grid/Class> Other examples that I found useful were the browser.ijs script in the SQLite addon, and the csvedit addon. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
