RD-VBA is an implementation of the MS-VBAL specification that is independent from its historical MS-VBA runtime host. RD-VBAL is the name of the specification/documentation of the language server platform, which includes the RD-VBA language core but is wider than the sole language specification.

🎯 The formalization of RD-VBAL is a work in progress.

This platform specification presents a similar technical prose style as its inspirational Open Spec source material.
