Scott, do you have an externally-described DS for your LIKE fields in
one program and not the other?  That could cause a field that is zoned
in your file to be zoned in one program and not the other.  (See here
for the reason why this happens
http://faq.midrange.com/data/cache/56.html)

The way I would fix this is I would add a qualified or prefixed
externally-described DS in the /copy file with the prototype, and code
my parameters LIKE the ext-ds subfields.

   * prototype /copy file
  D myfile_types       e ds            extname(myfile) qualified
  D                                    based(type_dummy)
  D getlast              pr            extpgm('PRR353')
  d  ssnox                             like(myfile_types.ssno)
  d  best                              like(myfile_types.last)
  d  prvsupssn                         like(myfile_types.supssn)
or
   * prototype /copy file
  D                    e ds            extname(myfile) 
  D                                   
prefix(myfile_types_)                                
  D                                    based(type_dummy)
  D getlast              pr            extpgm('PRR353')
  d  ssnox                             like(myfile_types_ssno)
  d  best                              like(myfile_types_last)
  d  prvsupssn                         like(myfile_types_supssn)
