Is that the ENTIRE snippet?  It looks to me like it goes to all the work of storing the dirs and all, but never does anything with them.  you sure there isnt something else you forgot to put in, in update.c or something?

If I were to code this from scratch in SMAUG i would use skill timers, see for example do_dig, do_search.  But I'm not sure if your codebase has that ability (it looks very similar to smaug so it might)

On an unrelated subject, these jog/jet/run commands are utterly stupid and never ever ever work well.  my recommendation is, leave it the heII out.
