We still support it being there (after all we "own" the registration of the slot), but we mostly use the name/token facility now (one for the subsystem and one per product, and then each of the products has between 1 and "many" that can be active at a time). Actually our IBM anchor points to a Vtable which includes those name/token addresses (we didn't trust the name/token facility at first so we keep track of everything we do with them 'just in case") and we have a name/token that points back to the anchor (just in case). There are advantages to the anchor entry, but one problem we kept running into was that not everyone registered their use with IBM, and apparently we had some people's favorite offset number, so occasionally we would have people step on us. Debugging who that was was not always easy at all. Especially when it was something that one of the local site sysprogs "copied" from one of their old job sites. So, while the anchor is very useful and quite simple to maintain, so are name/tokens and we don't have to ask anyone to use them. If you are marketing software that can use the anchor, I highly suggest you ask for a slot, but you may not end up using it to the extent that you think you will. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
