The code is available on the NEC Archives ftp site. The ftp site name is <#341#>ftp.netcom.com<#341#>, and the code is in <#342#>pub/rander/NEC<#342#> directory as <#343#>wiregrid.zip<#343#>. The code was compressed using the widely used DOS shareware utility <#344#> PKZIP<#344#>; use <#345#>PKUNZIP<#345#> to decompress. Details on downloading codes from anonymous ftp sites may be found in any of the many guides to the Internet now appearing. To summarize, proceed as follows:
There may be an appreciable delay (possibly a number of seconds) between entering a command and obtaining a response, especially if you are accessing the site from outside the USA. South African users should note that <#356#>wiregrid.zip<#356#> is mirrored on our local Stellenbosch ftp site, viz. <#357#> ftp.sun.ac.za<#357#>, and should download from this site in preference to <#358#>ftp.netcom.com<#358#>.
If <#359#>PKUNZIP<#359#> cannot unzip the file, check that you have a sufficiently recent version (the index entry for WIREGRID details the version used); if this is not the problem, you may have done a ftp transfer in ASCII mode en route to your PC. Your local Internet guru will be able to advise!
For installation, all files on the distribution disk should be copied to a directory of the user's choice. When <#360#> wiregrid.exe<#360#> is run, it will prompt for the directories where the wire grid models and the NEC2 input files are to be stored respectively. Several example files are included with the <#361#> zip<#361#> file. The user may change these directories during a session, and these changes then become the defaults for the next session. Whenever a directory which does not exist is specified, it will be created on request.
