Hello Richard, John and Jim, First, Thanks for the info. I downloaded TP55 via the link. Good thing that Embarcadero (sounds 100% Español) makes available older versions of popular software. One of the options I had in mind, was to use an older version of Delphi. I prefer this above VB. Structured design isn’t strange to me, so Pascal, is still attractive for me (though it is not as popular as years ago). My lecturer for high level programming was Mr. L. Ammeraal. I know Turbo Pascal was very popular. Later, many people I know used also the Delphi product (both free time and professional SW development). After that some people switched to C++ builder. Best regards, Wim PA3DJS www.tetech.nl forget abc and you have a valid mail address. |

Hello, I made an excel sheet to simulate Fresnel diffraction patterns. I used a 2 way data table to generate the "infinitesimal" contributions from the EM field. After summation of the contributions in the 2D tables, a have one result cell (that holds |E|) and three input cells (variables) for x-, y-, and z- coordinate for the observation point. When I change the coordinates manually, the results seem OK. The idea was to use another table (one way table) to plot |E| versus one of the input cells. However, I cannot get the table working. *I tried "scenarios" (filling in each scenario by hand), but Excel stores the individual worksheets, so I ran out of the EXCEL 2000 internal memory limit (I think of about 60MB). I also tried the offset function, in combination with a one-way table. This also didn't work. It seems that once you use a data table that uses one (or two) of your variables, you cannot use another table to manipulate a third variable (parameter). Does somebody know a solution for this (I do not prefer a VB one)? Best regards, Wim PA3DJSwww.tetech.nl The PM is valid when you don't forget to take out abc. Hello contributors to my Excel problem, Though I am not an SW guy, I solved my Fresnel diffraction problem with Turbo Pascal 5.5. After playing with some basic Pascal things, it took limited time to write the routines. The speed of the calculations surprised me. I think they did a really good job at that time. For the time being, I use MS excel for the graphing part. Thanks for the help! Best regards, Wim PA3DJS www.tetech.nl When leaving out abc, you have a valid PM. |
