When an init is built, the VA FileMan version number of the source system is put into the init routine. When the init is run, that version number is compared to the version number of the target system that is stored in the MUMPS OPERATING SYSTEM file node, ^DD("VERSION"). If the init was built using a version of FileMan later than the one on the target system, an error message is displayed and the installer is not allowed to continue running the init.
This precaution is necessary because a newer version of VA FileMan may contain features and DD structures that are not recognized by previous versions. Trying to use the new features or to install the new structures on an older system could cause the installation to fail or to produce undesirable results.
