If there's one thing I'd wish for, it would be for a standard
encoding of binary 36-bit data into octets. FTP uses high density
format. Magtapes use core dump format. ITS files and itstar use the
evacuate format. Then there's the ANSI-ASCII/KERMIT-36 5x7+1 format.
Let's not bring up disk images or 7-track and paper tapes.
Personally, I'd vote for coredump format, as it's the common
denominator among Tops-10 and its derivatives (SAIL's WAITS,
Tymshare's TYMCOM-X, the CIS monitor) and TOPS-20, with utilities to
convert into the others if necessary (which it rarely is).
If we're casting votes, I'd put mine on ASCII-ANSI. Because:
- PDP-10 7-bit ASCII files are transformed into 8-bit ASCII files.
- It's simple.
- Words are always encoded into 5 octets.
With one bit lost... (7*5 == 35)
Maybe I'm missing the point here, but if you want to handle anything
except 7bit text, then I think this format would fail...
