You are working too hard.  You can tell the VAX Ada compiler not to create
the .ADC files in the first place by using the /NOCOPY_SOURCE qualifier on
the ADA, ACS COMPILE, or ACS RECOMPILE commands.  From the on-line help text:

| $ HELP ADA /COPY_SOURCE
| 
| ADA
| 
|   /COPY_SOURCE
| 
|    /COPY_SOURCE (D)
|    /NOCOPY_SOURCE
| 
|     Controls whether a copied source file (.ADC) is created in the current
|     program  library  when  a  compilation unit is compiled without error.
|     The RECOMPILE command requires that a copied source file exist in  the
|     current program library for any unit that is to be recompiled.
| 
|     By default, a copied source file is created  in  the  current  program
|     library when a unit is compiled without error.
