Aucbvax.6916 fa.info-vax utzoo!decvax!ucbvax!info-vax Mon Apr 26 09:02:02 1982 VMS terminal I/O >From mknox@UTEXAS-11 Mon Apr 26 07:32:01 1982 I am attempting to post a VMS QIOW read to the terminal with a different set of terminator characters than is standard (as per the I/O Users Guide). The relavent code is: . . trmchr: .quad 8 . . . $qiow_s chan=chanl,- func=#(io$_ttyreadall!io$m_noecho!io$m_timed),- p1=buffer,p2=strlen,p3=#120.,p4=trmchr . . . The problem is the P4 parameter. It causes the routine to blow up with an access violation, unless trmchr contains a 0. In any event, the termination characters remain unchanged. What am I doing wrong??? tnx MKNOX at UTEXAS-11 -------
