This warning "WARNING: The quoted string currently being processed has become more than 262 characters long.  You might have unbalanced quotation          marks." is a very red flag; it can generate all sorts of other errors and strange behaviors.  Somewhere you have unbalanced quotes.  I suspect the problem is in your autoexec.sas file and not in the code itself and that you are getting it in the second run because you have not closed SAS in between runs.  Bring both of them into an editor that color codes comments and it should pop out at you (The one in EG 6.1 does fine.  I think SAS Studio would show it too.)
