Title: RE: sial output redirection

Luc,

I have to post an updated patch because I overlooked one case in my original test – the output redirection was left enabled after the sial command completed.  It caused subsequent sial commands to be redirected (undesirable).

 

This update saves and restores the original fp at the end of a redirection.  Sorry...

Very useful thing to have. Looks good. Dave can you queue it?

Luc,
The following patch will allow the output of SIAL commands to be
redirected to a file or pipe.  I did not handle all cases supported by
crash (e.g. multi-pipes), only simple output redirection.  Would you
please consider this change or something like it in the next release?
Thanks.
