It is used to determine whether or not the format of the
file matches the format the parser understands.
For UNIX, the parser used to be able to switch formats
on the fly. That is version n of the software could parse
the file formats for version n, n - 1, n - 2, ... 1. With
V4.0 we decided to cripple the product (i.e. make it more
like VMS :-) So for V4.0 if your init file does not say
4.0 then we bail out immediately. What that means is users
have to do an extra step to convert their old initializa-
tion files to the new format. If users are coming from a
very old version they may have to do multiple incremental
conversions to get to a parsable V4.0 file.
