Sub Articulo 88.0

 I am using osa.bst in conjunction with revtex.cls (using LaTeX 2e).
 
 1. I have entered my refs in BibTeX .bib file. The article titles are
 entered in Upper and Lower Case in Normal Title Style. I did it that way
 [...] When I use revtex.cls and
 osa.bst the article titles are printed in Upper and Lower Case. HOWEVER,
 by looking at a recent issue of JOSA A (journal I am writing for) I find
 that the article title should be in lower case (as in a sentence).  Is
 there a problem with the osa.bst file?  If so, how to fix it?
