do...except Statements

You can use GUI specifiers to enclose an entire do...except statement before individual statements, but you cannot use GUI specifiers before the except clause.

// legal: 
do
   mswxp Verify (expr1,expr2)
   mswin7 Verify (expr3,expr4)
except
   mswin7 reraise
   mswxp if (ExceptNum () == 1)
       Print ("err, etc.")
// NOT legal: 
mswin7 do
   Verify (expr,expr)
mswxp except
   reraise
