Subject: RE: regex: move minus sign to front for negative numbers w traili	ng " -"

Hi sir Guy,

that was very helpful and very quick, too (within a few min, i got a working
answer).

1. I have "engraved" your name in "my" code (i will use the code in
production to convert legacy apps output). 
2. I have to study more on ruby regex since (upon looking at your regex)
some of it is new to me (and hoping someday I may help someone, too :-)

Again, many thanks.
