What is TV++?

TV++ is a 4690 File utility that runs on Windows and allows you to view and manipulate records within a 4690 Tlog or Keyed file.

In addition to understanding the file formats, TV++ has been designed to be extendible and provide detailed field information for records which it encounters. Essentially, TV++ is a file browser that allows you to “see inside” 4690 Tlogs and Keyed Files in a visual manner.

TV++ allows you to not only view data with a Tlog or keyed file, but also define layouts for the records and fields of that data and have TV++ breakout the fields and show them in a meaningful fashion.

This approach allows you to do things like assign text to a bit field. For example, you could assign “Price Change Occurred” to the 3rd field, 4th bit of a 01 supermarket string. It supports sorting and filtering of records, and even allows you to save any combination of them off into a new file (in either append or overwrite mode).
