Subject: Re: Perl calling C-subroutines (VMS)

You may want to take a look at the files in:

http://www.cpan.org/modules/by-module/VMS/BHUGHES/

Here you can find the Perl module VMS::IndexedFile.  This
Perl extension may do exactly what you need.  If it doesn't
it would provide an excellent example of Perl/C integration
in the area of RMS Indexed file access.

You may need to read the Perl documentation on Xstut to
understand the mechanics of this integration.
