The error message is caused by the variable name "digit1".  The same error
message is produced by Sun's version of csh.  "i1" fails as well.  So, in
spite of the manual claiming that variable names consist of letters,
digits, and underscores, it does not seem they can end with a digit.  Seems
like a bug to me.
