Example Code
/* add RxUsbQueryVersion */
rc = RxFuncAdd('RxUsbQueryVersion','usbcalls','RxUsbQueryVersion')
say '+RxUsbQueryVersion(),RC=0x'd2x(rc)
/* invoke RxUsbQueryVersion */
drop DLLMajor DLLMinor /* receives usbcalls version */
drop USBMajor USBMinor /* receives usbresmg version */
rc = RxUsbQueryVersion(DLLMajor,DLLMinor,USBMajor,USBMinor)
say '*RxUsbQueryVersion(),RC=0x'd2x(rc)
say 'USBCALLS 'DLLMajor'.'DLLMinor
say 'USBRESMG 'USBMajor'.'USBMinor
/* drop RxUsbQueryVersion */
rc = RxFuncDrop('RxUsbQueryVersion')
say '-RxUsbQueryVersion(),
