HP-3000 compatibilty features.

Compiler directives.

When the HP-3000 compatibility option is enabled, the Kobol compiler will do an extended search for files in $INCLUDE directives and COPY commands. The compiler will first search the file with the name exactly as entered. If it is not found then a search will be made for the downshifted name, then for the upshifted name, then for the name stripped from group and account information, and finaly for that last name chopped to eight characters.
