For an individual name, you could use "whereDefined" to good effect:
whereDefined=: 3 : '(4!:4{.;:y) {:: (4!:3''''),<''Source of definition
not found for '',''.'',~y'
whereDefined 'calendar'
E:\Users\DevonMcC\j64-804\system\main\stdlib.ijs
whereDefined 'calendar_z_'
E:\Users\DevonMcC\j64-804\system\main\stdlib.ijs
load 'dt' NB. Load my own version of "calendar"
whereDefined 'calendar'
E:\amisc\Jsys\user\code\datetime.ijs
whereDefined 'calendar_z_'
E:\Users\DevonMcC\j64-804\system\main\stdlib.ijs
