Thanks Bill and Nick, this is very helpful.

Nevertheless, the reason I'd like to change the format on
c(current_date) is to incorporate it into the name of a file.  What
I've been doing is:

     local c_date= c(current_date)
     local date_string = subinstr("`c_date'", " " , "-", .)
     save "`date_string'_example", replace

Which yields a file name 22-May-2013_example

I'd like a file name that is more like 2013_05_22_example

Incorporating your suggestion I get:

     local date= %td_CCYY_NN_DD date(c(current_date), "DMY")
     local date_string = subinstr("`date'", " " , "-", .)
     save "`date_string'_example", replace

But after the first local macro I get an error that says

     %td_CCYY_NN_DD invalid name

Any suggestions on how I could fix this?

Thank you so much!

Melanie
