Visual Logic 2.2

Visual Logic 2.2 has arrived, and here are some of the highlights of the last two versions.

NEW FEATURES WITH VISUAL LOGIC 2.0

NETWORK/LAB INSTALLATIONS

Visual Logic provides a generous installation allowance. When you adopt Visual Logic 2.x, you can download and install the software as broadly as you want, including on your campus network, in your labs (regardless of the number of machines), and on student and faculty home machines. Students can even download and save the Visual Logic program on their USB Thumb drives and run the program on any Windows PC anywhere.

WORK AUTHENTICATION (Signature Files)

With Visual Logic 2.x, a student obtains a license to use Visual Logic with the purchase of a PIN code. The student visits the Visual Logic web site (www.visuallogic.org/course) to consume the PIN which creates a personalized Signature file (VLSig) that uniquely identifies that student.

Each time a student runs Visual Logic, the session is authenticated via the VLSig file. All work done during that session is tagged as being authenticated by that specific student. Instructors can verify who authenticated the work when they grade the files.

NEW FEATURES WITH VISUAL LOGIC 2.1
(NOTE: All 2.0 files will work with 2.1 and vice-versa.)

TRACE FILES

Testing is essential to writing good software. Good developers come up with good test cases. Visual Logic supports this notion by encouraging students to create a test file, and then generating a Trace I/O showing the program results for the test file.

  1. The first step is to use Notepad or some similar text editor to create a text file named "input.txt". The file should contain one data input per line. Save the input.txt file in the same directory as your solution file (.vls).
  2. Select "Tools | Testing... " to run your program in Trace mode, creating a TraceIO.txt file.  Open the trace file to view the program run.

Note: A varient of the trace file option can be used by Instructors to grade students' work faster and with more accuracy. For more details, see the Information for Instructors document available through your Course Technology sales representative.

TEXT TO SPEECH SUPPORT

A new, fun twist introduced in version 2.1 is the VL Text To Speech functionality. When you run your Visual Logic program you will not only see the output, but you will HEAR it as well. This is another example of how Visual Logic makes programming both Fun and Easy! (Note: Text-to-Speech (TTS) functionality requires appropriate configuration on your PC.
