I think it's just a limitation on single-line messages. Even if you 
split it up into two statements separated with a semicolon, it doesn't work:

  get whatGives(random(999)); put it into fld "myFld" -- fails

If you move it to the multi-line message box, the one-line statement 
above still doesn't work, but if you split it into two lines, it does:

  get whatGives(random(999))
  put it into fld "myFld"

The message box uses a "do" statement to execute its commands. As a 
guess, maybe there's a limitation on the number of nested functions the 
"do" command can handle simultaneously.
