When set (and TXF_EOT not set), the initial cursor position for an editing session will be determined by the TXC.XROW and TXC.XCOL parameter (if both are non-zero), or else by TXC.XCUROFFSET. This can be useful when you want to start an editing session at some location other than the start or end of the text, and when searching (see TXC.SRCHKEY) to establish the initial position of the search operation.
