What do I have to do to use the dynamic mdisk feature of listserv ? I have set up the following but listserv keeps using the FILEDISK mode. (if I change FILEDISK to F, listserv tries to put the file on the F disk) Assuming I get it to work, will listserv 'release' the disk when it is through ? Also, in the MITTST FILELIST header, can I restrict the files access to members of a LIST ? i.e. *+ SOM=(list=MYLIST) Another question.... what is the syntax of parms that I can use in the headers ???????? LOCAL SYSVARS ---------------- FILEDISK = 'A5' MDISK.222 = '* N L L 85 95 //(222) is a Dynamic Disk.' CHECKMDISK = '191 192 222' LISTSERV FILELIST ----------------- /F/ MITTST FILELIST ALL OWN V 104 26 89/05/01 12:01:48 General Info MITTST FILELIST ----------------- *+ SOM=(list=MYLIST) NEWFILL TST SOM OWA V 80 16 89/05/01 12:01:39 Office of.......
