The main problem with system() is the lack of error reporting if one of
the commands fail for some reason. I have written two special routines
that use system() and the special features of 4Dos to capture stderr
output, exit code of internal commands, and exit code of external
commands. But these routines are kludges. If there were a system type
function that could capture and return such information, it would be a
step forward.

One possible example, using 4Dos.com:


sequence errinfo
errinfo = systemcap("Rename MyFile ThisFile",?)


errinfo would contain {atom, atom, sequence}
that is, {External exit code, internal exit code, sequence containing
stderr}

Its been so long since I worked with Command.com, I can't remember if
there is a way to get exit code info on internal commands. If not there
would only be one atom.

In any case, the return sequence would have information about success or
failure that could be analyzed.
