Proposed Change to Host/IMP Spec to Eliminate Marking

Before he left for Norway, Dave Walden observed that there was a

simple change to the Host/IMP specifications which would eliminate all

"marking" problems. The change is to separate the leader from the text

of regular messages, and then to send them as consecutive messages

instead of one packed message. The text would then start on a word

boundary no matter what the word lengths of the machines involved. The

process would take place on both IMP-to-Host and Host-to-IMP messages.

We can see no disadvantages to this scheme, and a sampling of Host

reactions range from neutral to wildly enthusiastic. Therefore, we

tentatively plan to implement this change. We recognize that this

change will involve Host program changes, and that the new release must

be scheduled to coincide with those changes. We propose providing

modified Host spec text along with a one week notice of the new release.

If anyone sees a flaw in this scheme, or is unhappy about it, please

contact BBN quickly, since a new version of the IMP program is already

in the works.
