[TUHS] Query on PDP-11 assembly

[Naoki Hamada]

Hi,

This technique was a very common one in assembler sources for PDP-11
versions of UNIX. For example, m40.s of Version 6 UNIX shows a line
"jsr     r0,call1; _trap" in its trap routine. I feel very funny to
tell this to Warren, the author of apout!

Anyway, it could be a source of the null-terminated expression of
character strings of the C language, I guess.
