Well, in 4.5 there was a similar problem about an unresolved external, in that case an 'X' initialization routine. Fortunately, the same routine could be found in the static libraries (RL) in LIB.SYS, and it was a simple matter of extrating that one routine, and either loading it into your current init libraries or linking it discretely with your application. In either case, the routine was not significant for what we were doing. (Who is doing X clients on the 3000 anyway, esp on 4.0?) ---- Jim Wowchuk Internet: [log in to unmask] Vanguard Computer Services Compu$erve: 100036,106 _--_|\ Post: PO Box 18, North Ryde, NSW 2113 / \ Phone: +61 (2) 888-9688 \.--.__/ <---Sydney NSW Fax: +61 (2) 888-3056 v Australia
