A revision is a version
of a module. Each revision contains source code, an executable code
stream (optimized binary executable), and metadata. The metadata
describes the methods and method signatures of the module.
Revisions provide several
advantages, including the ability to roll back to a previous version
of a module.
SAS Micro Analytic Service
assigns a revision number to each revision, which is a monotonically
increasing integer beginning with 1. A revision is uniquely identified
by module name and revision number. When you reference a revision,
specifying revision number 0 selects the latest revision.
