Pioneer Report MDI is a GRML, CSV, and text delimited file and web browser. It reads files from local filesystems and web Seiten from websites. GRML, Allgemeine Reuse Markup Sprache, supports input controls for a form, (hyper-)links, images, and text. Use a form to send web requests. There are four file and web displays, Report, Horizontal List, Vertical List, and Thumbnail. Each displays allows editing, tooltips, cut/copy/paste, and saving.

GRML is a data-oriented format. It contrasts formats such as HTML or PDF, which are display-oriented. Other data-oriented formats include CSV or XML. They describe data content, rather how it is displayed.

Pioneer Report MDI has a history window, workspace explorer, details window, picture window, and navigation history. The history window contains all file and web page requests submitted. The details window displays information about displayed files and web Seiten. The picture window provides a resizabe area to view images. Navigation history is used to navigate file and web page requests using 'Forward' and 'Back' controls.

There is GRML 2.0 support. This is the smallest, easiest to parse, and easiest to read version available. File sizes are smaller, there are more formatting options, and options to make the markup langauge more human-readable. Data corruption is minimized.

GRML supports a "name" in its syntax. This supports dimensions in a file or web page. Viewing multiple files, or web Seiten (such as search results, product listings, or news headlines) is possible in one file or web page using a dimension for each. To create a dimension, content is given a "name". A drop-down list displays the available content by "name". To view desired content, select its "name" in the drop-down list for display.

Supporting multiple file and web formats, files and web Seiten are saved in different ways. Read GRML and save in CSV or text delimited formats. Or, read CSV or text delimited and save GRML. Read. Display. Edit. Save.
