The ?comment help-page available in the commandline (and Classic?) interfaces does not mention it. Setting up one's Maple prompt to be the empty comment (**) in the commandline interface is neat. It allows one to copy the entire text of input including the prompt and then insert it as runnable code. As noted in ?comment, the pasting will only work properly in 1D Maple input mode. It works handlily for inserting into the commandline interface, or into a Worksheet with 1D Maple input mode in Standard. My Linux ~/.mapleinit file now contains, <pre> interface(prompt=" (**) "): </pre> One could also put that inside a conditional using <a href="http://www.maplesoft.com/support/help/Maple/view.aspx?path=IsWorksheetInterface">IsWorksheetInterface()</a>, to get it in commandline but not in Standard. Someone pointed out to me that it is also documented in <a href="http://www.maplesoft.com/support/help/Maple/view.aspx?path=Preprocessor&term=include">?include</a> in Maple 12, where it also appears to work. (Your mileage may vary.) acer The latest comments added to the Blog Entry, Thread Safety 63064 Thu, 08 Oct 2009 20:06:50 Z acer acer Comment Prompt http://www.mapleprimes.com/maplesoftblog/36643-Thread-Safety?ref=Feed:MaplePrimes:Thread Safety:Comments#comment63065 Since I use many different versions of Maple all day, I extended the idea of a comment prompt so that I have version information at a glance.  I have the following proc in my .mapleinit <pre> setprompt := proc() local versionstring; if not IsWorksheetInterface()=true then versionstring := StringTools:-Split(ssystem("echo $MAPLE")[2][1..-2], "/")[-1]; if length(versionstring) > 5 and versionstring[2..5] = "aple" then versionstring := versionstring[6..-1]; end if; if not kernelopts(opaquemodules) then versionstring := cat(versionstring, "O"); end if; interface(prompt=cat("(*",versionstring,"*)")): end if: end proc; </pre> So that my prompt in Maple 13 looks like (*13*), or (*13O*) if I have modules set to opaque.  It does rely on your different versions of maple being installed in directories named ../mapleXX, so it is probably unix specific. If one were committed to not using the directory name, you could translate the output of version() into a release number using a lookup table.
