David:

You are right, end of long day. That was poorly worded. The gist is
"Does a script processed by qsh have a limit on the length of a command? If so what are the tricks to get around it? (continuation or whatever)"

I've run into limits on what the Windows 2000 command processor in terms of length of the command. I was wondering what limits are on a qsh command, particularly one built in a script.

Yes. Unix shells (which qsh does quite a good job of being) has a limit on the number of arguments possible on a single command line.

Usually the xargs command know about this, so you usually do something like

echo * | xargs echo

(where * gives many files, xargs then chops them up in suitable batches and append them to the command - here echo).

There is no limit in the length of the strings passed in the pipe, only on the command length.
