I used BP2 V2.6, only because I understood that version was intended for RSTS/E V9.6 - I will try BP2 V2.7 and see if it is stable on V9.6. I am still to discover which of the TAPs of RSTS/E V9.7 are worth trying. One surprise I encountered though on rebooting RSTS/E, BASIC/BP2 throws an error: $ basic/bp2 ?Unable to attach to resident library ?Can't find file or account I fixed this by executing these two commands (found in BP2INS.CMD): $ INSTALL/LIBRARY/NOADDRESS B26SHR $ INSTALL/LIBRARY/NOADDRESS B26SH1 Then $ BASIC/BP2 works again. So it is usual RSTS/E practice to add the install/library commands to [0,1]START.COM to "permanently" add the layered product to RSTS/E? I expected the install process to do this for me.
