If the primary address space has an appropriate AX so that access to the random address space would be allowed, another way to access its storage is to set it as secondary address space. The API to get the STOKEN is to SRB over and ALESERV EXTRACTH, though it does appear that the ASSB has it. -- Binyamin Dissen <[EMAIL PROTECTED]> http://www.dissensoftware.com Director, Dissen Software, Bar & Grill - Israel Should you use the mailblocks package and expect a response from me, you should preauthorize the dissensoftware.com domain.
