Nope.  Byte operations on the PDP10 architecture all go through a "byte

pointer" object that can deal with any contiguous collection of 1 to 36 bits

that doesn't cross a 36-bit word boundary.  It's the OS that had a

predisposition for five 7-bit ASCII bytes per word, in string operations.

Serial I/O hardware had to deal with other realities, but most of it was

slotted into PDP11 frontend processors so it sat behind translation software

anyway.  Interfacing 36-bit hardware with 16-bit hardware made for some

interesting programming (and interesting hardware!), to say the least.>>

So let's get back to the original thread here, what I said turns
out to be exactly right. The normal format for strings on this machine was 5x7 with one bit lweft over, and there was hardware support for this format. (I
did not say it was the only format supported, just that there was hardware support
for this format and that it was naturally supported in the hardware)

Now back to the original point, given that --- how would you map ANSI C, given
the claims that have been made (actually I can't find real justification
for these claims in the ANSI standeard, and neither can Ritchie)
