Please respond to this article in the appropriate news group. Our e-mail has been bouncing mail lately and I don't want to miss any of your valuable responses. We would like to know if it is possible to have/implement shareable images in the Unix environment similar to the VMS implementation with the LIB$FIND_IMAGE_SYMBOL library call. I believe the same functionality exists in Unix with dynamic binding, but this is a difficult topic to find information on in the Unix environment. For those not familiar with VMS, shareable images allow you to call a routine that you haven't actually linked into your executable. The above library call returns a pointer to the routine you request that you can then execute. This is especially nice for product installation where sites may have site-specific interfaces that share the same calling parameters, and by just looking at a logical or environment variable you can determine the site specific routine to call. This does away with having a separate executable for each site. Any experience or tips you could share about dynamic binding or shareable images in the Unix environment would be greatly appreciated!
