The enclosed tape contains the latest version of SED for the
VAX. I have also placed my latest copy of COMPIL on the tape as
a separate save set, though I don't know if it has changed since
the version I sent you. The changes to SED since the last tape I
sent you are described in SED.SHF; I started keeping an edit
history right after I sent you the last tape.
In this version of SED, I have enabled the global Passall mode
of terminal I/O. SED seems to be reliable now that we don't need
the ability to abort out of a loop, and there are advantages to
having ^Y interpreted by SED instead of by VMS. For those who
like the way it used to work, I have defined a SED$DEBUG logical
name. If SED$DEBUG is set to "YES", then SED runs in debug mode
and doesn't put the terminal in passall mode.
Several of the enhancements I outlined as future possibilities
on the last tape I send have not yet been implemented. For
example, SED can't yet use record-oriented devices (such as
mailboxes). The xon/xoff problem is not yet solved. (I've been
told that version 4 of VMS has a PASSTHRU mode that should allow
me to get SED to work right with xon/xoff enabled. But who has
Let me know if you find problems with SED; I'll try to get them
fixed. Meanwhile, happy SEDding!
