Dir.GetPart of Dir module

Syntax   Dir.Get (streamNumber : int) : string

Description   Dir.Get is part of a series of four subprograms that help users get directory listings. Dir.Get is used to get the file names in the directory. Each time the function is called, it returns the next file name in the directory. The names are not sorted. When there are no more file names in the directory, Dir.Get returns the empty string.

Details   If the Dir.Get call fails, then Error.Last will return a non-zero value indicating the reason for the failure. Error.LastMsg will return a string which contains the textual version of the error.

Example   This program prints a listing of all the files in the directory datafiles.

        var streamNumber : int
        var fileName : string
        streamNumber := Dir.Open ("datafiles")
        assert streamNumber > 0
        loop
            fileName := Dir.Get (streamNumber)
            exit when fileName = ""
            put fileName
        end loop
        Dir.Close (streamNumber)
Execute  

Status   Exported qualified.

This means that you can only call the function by calling Dir.Get, not by calling Get.
