What is a MAS file?
Game file used by rFactor, a racing simulation game; stores the asset files for a racing track map and includes files for both the structure and the appearance of the track; can be modded to create custom tracks, but modding is only for advanced users.
MAS files can be opened with the gMotor MAS File Utility (MAS.EXE), which is part of the "rFactor mod development tool pack" available from the rFactor website.

Access Stored Procedure
2.0 | 3 Votes
Stored procedures are pre-written, embedded database commands that allow applications connected to a relational database management system, such as Access, to perform common functions without including those functions in their own code. This allows developers to streamline their application code, by referencing the stored procedure in one or more apps' code, rather than writing it out each time it is needed.
In most cases, Access saves stored procedures within the database with which they are used, and not as separate files. However, on occasion, you may see Access stored procedures saved as MAS files.
How to open a MAS file
You can use Microsoft Access to execute the procedure a MAS file contains (provided you have access to a compatible database).
