[tex-k] "char" type in tex.web

[Igor Liferenko]

Hi all,

I figured it out:

tex.web was made for Pascal where "char" type is 8-bit.
It follows from the fact that "char" is the same as "text_char" (§19)
and "text_char" is 0..255 (§19).
And §521 is in "system dependencies", so everything is consistent.

Regards,
Igor
