st: command for easily accessing a directory

["Jun Xu" <mystata@hotmail.com>]

I have been off Statalist for quite a while and am trying to re-gain my 
knowledge about Stata and keep up with the new stuff. I remember there is a 
command/package that can give users easy access to a directory especially 
when we need to change computers a lot. For example, if I have a data saved 
under c:\data\ecls\....

then I can just type "c ecls", then I will take that directory 
(c:\data\ecls) as my working directory in that session. I think that command 
starts with c, but I cannot find it (using findit or search statalist serve) 
now. Anyone could help me on this, or let me know if you have better 
alternatives. I should've taken notes about it before my major career 
transition.

Thanks,

Jun Xu
