The solution depends on what exactly the "this" is you are trying to perform. If you are referring to parsing out the contents of a file, WinBatch offers several ways of performing that task including loading the file into a binary buffer. If you are referring to displaying the contents of a portion of a file, WinBatch offers several ways of performing that task too. For example, you could consider creating a WIL dialog.
Also, you can control the maximum file line length with IntControl 65. Check it out in the Consolidated WIL Help file on your system or by going to the WinBatch Documentation Website.
