i don't agree. if the language is already parsed then you have the strings. the contents of the strings will have to be finite if they are fixed strings. so to convert a fixed string you can choose a type for the value and run a test to see if it works. if it does then you've picked the correct type, if it doesn't you pick the next type. there are only a finite number of types. yes it is brute force but it would find something that worked eventually if there was something to be found. for programs using indefinite strings via input you can't predict what those would be doing, but then of course you would be able to say the most general type could be tried first and then run tests to see if it worked. the overall patterns to try for a string could be driven by examining code which has already been converted that contains similar patterns - eventually you would have enough of an idea of which things to try first to speed things up. yes, this is a generally hard issue if you are talking random strings and not sure what is what, but in the case of a computer language it is already specified and parsers already exist. songbird -- https://mail.python.org/mailman/listinfo/python-list
