SV: feature request: only set RT when RS is found

[Ole Petter R?nningen]

Indeed you are correct. It is simply an embarrassing error on my part - I 
*thought* I had verified it with a test program, on closer inspection the 
blunder is all mine. My sincerest apologies.

Emne: Re: feature request: only set RT when RS is found

Hi. Thanks for the note.

As Ed pointed out, RT is always set, no matter what the value of RS is.
It is set to empty when no matching record separator is found, again, 
irrespective of the value of RS.

If you have a test program and data that can prove otherwise, please submit 
them here.

Thanks!

Arnold
