Function KeyRead() Foundation
Retrieves the key codes that have been read from the event queue already.
KeyRead() --> cKeyCodesReturns a string of max. 32k that contains key codes which have been read from the event queue already.
This function exists for compatibility reasons only. A key code is build from its ASCII code and the keyboard scan code. This can lead to problems especially when programming in GUI mode and/or using different keyboards. It is strongly recommended not to use KeyRead().
NOTE: The KeyRead() buffer is only cleared when KeySend() is called. In contrast to CA-Tools the command SET TYPEAHEAD TO does not clear this buffer.
