Every application should be given a version number which should appear in the header. This version should be assigned to a character variable or constant and should have the form:
'applic_name Version x.y-z'
where 'x.y' is the ASTERIX version number and 'z' is the version of the application within that release. A completely new application should be given the number of the next ASTERIX release, obtained by invoking the application 'RELEASE'. The application should be given a new application version number every time after its initial release that a change is made. The change should entered in the 'History' section of the header.
