External names on the HP 9000 workstations and servers do
not contain a leading underscore. You need to change any programs
that rely on external names containing leading underscores. Note
that all languages on the HP 9000 workstations and servers follow
the same convention. Therefore, only assembly language code and
names that were aliased in other languages are affected by this.
Because there is no leading underscore, external names contain one
additional significant character. Identifiers that differ only in
the 255th character will denote different items on the HP 9000 workstations
and servers.
