I was able to connect to the iSeries with cmd.exe but every command I tried failed. When I thought to use PowerShell, the exact same command that failed in cmd.exe worked in PowerShell. I don't have access to any other SSH servers so I don't know if it is iSeries specific or every SSH connection.
I will try the escaping of the ( and " tomorrow and report back.

1) ssh exists in Windows 10 but it only works with the iSeries (not sure
about other systems) when run in PowerShell. I could not get it to work
with command, with or without admin.
Are you saying you couldn't get ssh to work at all from cmd.exe or just
that it couldn't connect to the IBM i server (but could connect to other
servers)?
2) If there is a $ in your library or program name, the call fails. All
of
my development libraries begin with a $ so I can do a backup of $*.
You need to escape it or put it in single quotes:
echo \$mylib
echo '$mylib'
echo "\$mylib"
3) It does not like the "(" when trying to specify "parms() for the
call".
Parenthesis are special characters for bourne-compattible Unix shells.
These also need to be escaped as above.
4) I was able to pass a single parm ('system "CALL MSSUTILS/HELLOWORLD
John"') but did not figure out how to pass multiple parms.
5) When passing a parm, it converted it to uppercase...in the above call,
John became JOHN.
This is standard behavior for un-quoted strings when passed to the CL
command line (which is basically what system does). You'll need to put
those in single quotes if you want to preserve case:
"system \"CALL MSSUTILS/HELLOWORLD 'John'\""
Notice that you can escape double quotes inside a double quoted string
from bash, but single quoted strings do not allow escaping. Since CL
strings *must* be single quotes, you have have to use double quotes for
the outer string, with double quotes around the argument to system, and
then single quotes for the argument to MSSUTILS/HELLOWORLD.

Thanks again for all of the input.
For anyone playing along, here are some things I have stumbled over.
There
may be ways around them but I didn't dig to find the answers. If anyone
has
the answer, please feel free to pass it on.

sure
about other systems) when run in PowerShell. I could not get it to work

OK, great. So what is your plan on the Windows side of things? Is it
other
people developing the Windows script, and they are telling you that they
want SSH?
Or will you be responsible for the Windows script as well?
If it's other people, do you happen to know what they are using to
develop
the script?
