No, he's right. He's reffering to the chp_drlk entry, which must point to a fake driver definition block (only iod_clos needs to be set, which will be called when the memory gets freed). Actually this is exactly the way the thing system works, too. Check out util_thg_usage_asm, specifically th_addu. >> What is not trivial?

Actually I've never used them either. Marcel _______________________________________________ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm
