To be more precise, no. UniVerse Basic is a run-time typed language (like PHP) not a string language. So it gets the performance and storage benefits of real types, and coerces between types under the cover. If you say For I = 1 To 10, and examine I in the debugger, you will see that it is an integer, not a string. If you later say I="FRED" it will be coerced into a string, as will I := "FRED" or I<2> = "FRED". In addition to file variables, there are plenty other structures that are not coercible into strings: select list handles (from EXECUTE statement, SELECT. > SOMELIST), XML DOM handles and BCI context handles to name but a few. It may seem pedantic, but these distinctions are important when selling the benefits of language like UniVerse Basic. The word 'untyped' offends some sectors of the programming community. 'run-time typed' is generally more acceptable. (and it's funny how many developers sneer at the first mention of these, until you follow up with the PHP analogy.. and suddenly they see the light).
