What does "printing binary" mean?

I tried "H tq att". Didn't work, humm I think I have 3.9. I will
look for a newer version.
You may need to build from source; I suspect that
new tape mode
is a fairly recent addition. Package repositories are notorious for
lagging months or years behind, and simh is under fairly rapid
development these days. (thanks Mark!)

Hum ok I compiled simh-master.zip. The source I had I compiled using
gcc was from http://simh.trailing-edge.com so it might've been old.
This newer one is slower but I see the new help tq attach options. I used "set rq0 ra92" and "att rq0
vms" a new file was being created and that
took the longest. Before getting to the backup part of creating from the
openvms73.iso backup.
The latest code provides more robust/consistent behavior for simulators
when the simulator user interacts with it. In this particular case, the
complete disk image is created at attach time instead of having it
arbitrarily grow while the simulator is actually running. Arbitrary
expansion of the disk image while the simulator is busy executing
instructions can create crazy errors if/when the host system runs
out of disk space. It is best to find this out at attach time rather at
some random time later. This approach also supports subsequent
automatic disk type/size detection when you happen to restart the
simulator later. You'll now notice that later attach operations of
VMS (and most other OS disk images) will announce the disk label
and it's file system size when you attach a disk that has a ODS1,
ODS2, RT11, Ultrix partition table, on it.
Feel free to report any problems or other irregularities you may
observe.
