哎,我看了里面的help文档说
这个软件的第一版是1995年的,那时候是在DOS下运行的。还是QB的,嘿。
然后用到windows平台上来的。
再后来有3D
你说的美国军方的,是哪里说的啊?
The first version was developed in the year 1995 under the DOS operating System with the Q-basic language. In the following year it was ported to windows-95 and modified to run with the visual basic 3.0 version. Unfortunately this visual basic version was based on the older 16-bit operating system layout, so real ?
multi-tasking?was not supported. Version 4.0, was the first 32 bit version. With this version the NEC-editor, variables/symbols and the optimizer were included.
Later on, new versions with additional features and possibilities were created such as a real-time 3D viewer and a graphically based geometry-editor and provisions were added to also read/process Nec-4 based in- and output-files. The name 4nec2 however was not changed, but it should now be seen as 揻or NEC too? meaning another piece of software to use with NEC. |
