The transcript pad is actually a disk object (containing the text) which is mapped onto the display. As a disk file, operations like "clear to end of line" or "enable highlight" just don't seem to be appropriate (:-). Thus, the vt100 emulator reads the output from a program, parses it for control sequences, and "paints" the characters into a graphic object. You'll also see programs like "vctl" and "vsize" which give the ability to query/modify some of the behaviors of the emulators. Sorry that the "short answer" is "no cursor control on pads", hopefully you understand the WHY now. ...walt...
