It is strange. AEARN received it's copy via AWIIMC11. Here at AWIIMC11 the CODE_1.5O installed without any problems. At AEARN the error ocurred after LSVSTOP EXEC has been read. Oh yes, and AWIIMC11 got the copy from CEARN. Christian P.S.: the "half-installed" 1.5o made it impossible to start LISTSERV. The reason was that (1.5o)LSVINIT uses a new option of LSVFILER. Since LSVFILER MODULE hasn't been received at that time the initialization failed. We cleared the situation by loading the 1.5o LSVFILER. Maybe taking the 1.5n LSVINIT would also have worked.
