Thank you, members of this forum. The responses have been eye-opening. ABOUT MN: "mn" is exactly what I want to aid in constructing script lines. Using it will prevent many stupid novice mistakes. I was busily implementing something like it in C++ but will now stop. J declared an error when mncode is loaded.
Here are the filesystem actions taken before loading mncode: - cd j602\addons - mkdir 3rdparty - cd 3rdparty - copy ..\..\..\tmp\mncode.ijs - copy ..\..\..\tmp\primitiv.ijs Here is the error: load 'c:\documents and settings\jonathan lettvin\j602\addons\3rdparty\mncode.ijs': |spelling error | 'old new'=.x. | ^ | replacetokens=: 4 :0 |[-230] c:\documents and settings\jonathan lettvin\j602\addons\3rdparty\mncode.ijs Once it's working, it would be nice to have a single statement that did the following: - display-mnemonics then execute-line. I will attempt to write this for myself, but welcome suggestions. It should be easy to write. ABOUT WEB/JHP: web/jhp fails to display images. http://olegykj.sourceforge.net/jhp/ Choose "OpenGL Simple" or "OpenGL Dynamic" The intended image display comes up as - a little red x in a little box on Windows XP running IE 7 and - a disappearing little box on ubuntu linux running firefox 3.08. Here is what I intend to do with jhp on my DayNightLamp server: - present image upload form to user - upload size-constrained image (temporary maximum of ~100KBytes) - process uploaded image with J script - display original and/or processed image - allow user to browse their own history of before and after images The preferred display is as follows, not as shown on the daynightlamp home page: - If the mouse is off the image, the processed image is displayed - If the mouse is on the image, the original image is displayed The intended use of JHP is to replace the existing PHP generating HTML to perform this display task. Here is a working example of this display task in action: - http://www.daynightlamp.com/html/J/ The image displayed on this page is output from an early primitive filter. Later filters make much better processed images than this. This is a work in progress, and all you see is pre-prototype experimental. The file upload form (but not the image display) will have this appearance: - http://www.daynightlamp.com It will be nice to retire the old mechanisms I use and go to a pure J approach. Thank you again for your responses. Jonathan D. Lettvin ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
