I know the earliest message, quoted below, was prefaced by an
allusion to an avoidance of a system API... However, seems kind of
silly to follow the first of the paths shown below, when the second is
so much more direct, eliminating the levels of indirection and any
associated difficulties from having introduced that indirection:
I have not used that Qshell API, but FWiW:
IBM i 7.1 Information Center -> Programming -> Shells and utilities ->
Qshell -> Qshell APIs
_i QzshSystem() - Run a QSH Command i_
The QzshSystem() function runs the specified shell command by spawning a
child process and invoking qsh in the child process. qsh interprets and
runs command and then exits.
The QzshSystem() function returns when the child process has ended.
*command (Input) Pointer to null-terminated string that contains the
shell command to run.

You can specify a QShell function on the QSH CL command. An example
might be if you want to put a directory listing into an IFS file.
QShell commands can be chained - so this would create the PF, then
run the ls command into it. The semi-colon let it ignore an error
like the PF already exists. I don't remember what separator makes it
stop on an error.
qsh cmd('system "crtpf qgpl/lsout rcdlen(255)"; ls > /qsys.lib/qgpl.lib/lsout.file/lsout.mbr')
To append to that file, use a double right-arrow.

I do a fair amount of RPG call to QCMDEXC but never QSHELL so
a simple example would really help. <<SNIP>>

Remember, anything you can do on a QSHELL or CL command line,
you can do in a CL or RPG program. (In the case of RPG, the
easiest would probably be to call QCMDEXC, which is still, for
most people, way easier than fiddling with system APIs.)
