Function searching, was: Bug in IBM Date Routies %month

Got a question.  Suppose you wanted to search all service programs for an 
exported function, how would one automate that?  For example, if I wanted 
to search for a last_day function how do I search the results of
DSPSRVPGM SRVPGM(*libl/*all) DETAIL(*PROCEXP)    \\ Note:  *ALL is not 
supported
 for a particular string or strings?  Let me guess, extensive use of the 
List Service Program Information (QBNLSPGM) api, combined with the list 
objects api?

Then I suppose the next question is how do I find all of the existing 
binding directories that have this service program in it?
