From: Provan@LLL-MFE.ARPA Can anyone tell me what the purpose of the /(no)carriage_control switch in the Set Prompt command is? As far as I can tell, the only difference this makes is that the prompt will go to the next line if you have your terminal echo turned off with the switch (the default), but it will come out on the same line if it isn't. There must be a more important reason. While I'm being puzzled over this, can anyone tell me why the leading <crlf> that's /carriage_control prepends to the prompt is discarded normally? For example, if I'm at the DCL prompt and type <cr>, one would expect, given that my prompt is /carriage_control, that there would be a blank line between the two DCL prompts, but there isn't. I'm not complaining, I just don't understnad why all this work is being done to append the <crlf> by making /carriage_control the default only to strip it when the prompt gets output. There is some (unwritten?) law at work here that I don't understand. Anyone know what it is?
