Vector is having documentation on CAPL script and also providing demo version of canoe and canalyzer. Without the Hardware, you can not check your scripts anyway.
But you will get CAPL editor and all. You can use it for easy understanding the script language...
Withour hardware (vector hardware) we can modify capl codes in acccordance with.
we can execute CAPL codes without hardware, but make sure that when we start application canalyzer /canoe we must have connected hardware to application,since application initially look for that license *which is available on hardware.. (it can be empty hardware without transcivers in it). u run application and remove harware which was connected to it.
