Woah!

I’m amazed, flattered, impressed, puzzled, wondering, etc. at the
same time. Please give me a bit to come up with a suitable reply,
this deserves some time to think about, and I love your enthusiasm.

My condolence! Rest assured I’m using FixedMisc [MirOS]¹ here.

FWIW, I'm quite impressed with mksh interactively. I thought it was much
*much* more bare bones. But it turns out it beats the living hell out of
ksh93 in that respect. I'd even consider it for my daily use if I hadn't
wasted half my life on my zsh setup. :-) -- Frank Terbeck in #!/bin/mksh

Oh, you're very kind!

mksh already has a remarkable track record of portability, and this
would be yet another feather in its cap. The build system, though
unconventional, turned out to be a lot easier to work with in the EBCDIC
environment than GNU Bash's.

By the way, there's one addendum I'd like to put here: It turns out that
NSIG=32 isn't quite right for z/OS. The system has a few more signals
than that, some of which appear to be unique:

$ kill -l
 NULL HUP INT ABRT ILL POLL URG STOP FPE KILL BUS SEGV SYS PIPE ALRM
TERM USR1 USR2 ABND CONT CHLD TTIN TTOU IO QUIT TSTP TRAP IOERR
WINCH XCPU XFSZ VTALRM PROF DANGER TRACE DCE DUMP

$ kill -l | tr ' ' '\n' | grep . | wc -l
 37 

$ grep SIGDUMP /usr/include/signal.h
  #define SIGDUMP  39

(SIGDANGER, Will Robinson!)

Do take the time you need to chew through all those changes, of course.
I'll be happy to pick things up again at your convenience.

Nice! If it weren't for the big Web-mail providers seeing fit to display
.signatures in variable-width fonts, there would still be a little ASCII
skunk down below ^_^
