GT.M V5.0-FT01 is available. This is a field test version that extends the length of names to 31 characters, adds a $Increment() function, and provides an option for a database to contain existing nodes with null subscripts while prohibiting sets with null subscripts. Please put it through its paces.

Krung Thai Bank is the second largest bank in Thailand. To the best of my knowledge, at over 14 million accounts, this GT.M based application is the largest single real-time core processing system in production at any commercial bank anywhere in the world.
