I wish to exapand a path to work with it
programatically. How do I do this ? I am going crazy trying to find a solution to this simple problem, PLEASE HELP!

(I.e what I want to do is for example
%expandpath(peppers) where peppers is a path I saved earlier)

Use %exec:
#SH %exec(.peppers)

Notice that the path is returned in stringlist form.

> #SH %exec(.peppers)

okay, this is the key to my current scripting scenario, but how do I expand a variable in place of "peppers"?

Example:

#trigger {&player tells you to visit area (*).} {
#var location %1
#show @{player}'s DIRs are: %exec(.@location}
}

yes, I realize (at least for the example above) that I could just use %1 throughout the #trigger, or perhaps even use "&%*{location}" instead if it might contain a semi-colon, but there are other places I want to use the %exec(.@location) scenario, like on the command-line:

#SHOW PATH: %exec(.@location)

if @location contains an area "name", for example, the above command does not expand @location at all, but treats it as a literal string. Instead, it should expand its value:

%exec(.@location)
would be translated, on the fly, to
%exec(.The Temple of Jello)
if @location, indeed, had the value of "The Temple of Jello".

Thanks for any suggestions...

I have no problem with making %exec expand a variable. Perhaps you can try forcing expansion:
#EXEC {%concat("#SH %exec(.", @location, ")")}

I would suggest you use the %defined function to determine if the contents of @location are actually a stored path. If they are not then you should use one of the room finding scripts in the forums and %walk to get a valid path.

THANKS, Kjata! worked like a charm with some minor editing:
[ so that all the | are replaced by ; ]
#EXEC {%concat("#SH %replace(%exec(.", @location, ")"),"|","`;")}

thanks, too, go out to Vijilante, for your reply... not that I exactly understand it, but thanks just the same. *wry smile*
