I have the same Set instruction twice in DAAD /PRO 11:
Adventuron (redescribe = auto_beta):

: match "get ladder"  {
   : if (is_beside "ladder") {
      : if (is_at "treestand") {
         : set_graphic graphic = "treestand2"  target = "treestand" ;         
      }
      : get ;
   }
}

DAAD:

/PRO 5
> GET    LADDE PRESENT ladder
              NOTCARR ladder
              CLEAR is_done_
              PROCESS 11
              NOTZERO is_done_
              DONE
/PRO 11
> _      _    AT treestand
              SET has_done_something_
              SET has_done_something_
              LET 18 255 LET 19 10
              AUTOG

The code for DAAD is wrong: AUTOG should not depend on the test: AT treestand; It is right if I set Get before the test:

: match "get ladder"  {
   : if (is_beside "ladder") {
      : get ;     
      : if (is_at "treestand") {
         : set_graphic graphic = "treestand2"  target = "treestand" ;         
      }
   }
}

/PRO 11
> _      _    SET has_done_something_
              AUTOG
> _      _    AT treestand
              LET 18 255 LET 19 10

The second set of generarated code looks good to me. The get is not dependent on at treestand.

You are right about the redundant sets, I'll take a look.

Another example with two equivalent Set, and an error because Get does not depend on the test: AT treestand.

redescribe = auto_beta
: match "get ladder"  {
   : if (is_at "treestand" && is_beside "ladder") {
      : set_graphic graphic = "treestand2"  target = "treestand" ;
   }
   : get "ladder" ;
   : done ;
}
> GET    LADDE AT treestand
              PRESENT ladder
              NOTCARR ladder
              SET has_done_something_
              SET has_done_something_
              LET 18 255 LET 19 10
              GET ladder
              DONE

This is certainly a bug, looking at it now.

Please can you try the new version.

I can't test with DRC and the emulator under Linux, but it looks good.
