PRO Format Description

The PRO format is a binary file format. As such, data in a PRO file cannot be read with a standard word processor. CRB provides PowerPro for viewing and editing these files. Only edit PRO data files with such an editor.

Each record in a PRO data file contains 26 bytes. The date is stored as a 2-byte signed integer. The rest of the fields are each 4-byte single precision values.

Typically the ticker symbol is used as the name of the PRO file.
