[TUHS] Other Bell Labs shells from the 80s?

[Arnold Robbins via TUHS]

Hello all.

The CL memo was interesting, in a way.  The notations are clearly
much more verbose than the standard shell, and I found that a little
off-putting.

The memo's references refer to Marc Rochkind's 2dsh --- Marc, whatever
happened to that? Are source and or the memo for it available somewhere?

Also it refers to a shell by Blewett and arder called Parser. Anyone
have that memo?

Just wondering,

Thanks,

Arnold
