Why not simply use the Berkeley rsh, rcp and so on ? Just copy the
script and data files using rcp ... and then execute the following
command file :

$ set symbol/scope=noglobal
$ host = "''p1'"
$ if P2 .EQS. "-L"
$   then user = "''p3'"
$        client = "''p4'"
$        command = "''p4' ''p5' ''p6' ''p7' ''p8'"
$ else   user = f$edit(f$getjpi("","USERNAME"),"LOWERCASE")
$        client = "''p2'"
$        command = "''p2' ''p3' ''p4' ''p5' ''p6' ''p7' ''p8'"
$ endif
$ rsh 'host'/user='user'/input=NL: -
  "exec ''command' < /dev/null >&! ~/''client'.log"

It will launch you remote command on the Unix station and let it execute. When
it completes you will find the results in the logfile *.log in the login
directory on the target host (you can even read the log file using
rcp remote-host:*.log tt:). Don't forget to setup the .rhosts file on the
target Unix host.

Another solution could be to port NQS to VMS ...
