Thanks all for the input it is appreciated. (especially as the question was so hastily/poorly written -- sorry 'bout that)

This is a heavily used set of scripts by diverse teams. While performance is not critical I like to do what I can to stay streamlined. It's dependence on $ENV has to do with its evolution from a family of ksh scripts that utilize about 30 environmental variables to control their functionality. I'm waying the pro's and cons of 'speed' to the production floor vrs code cleanliness and performance.

Me thinks I should just wipe 'em all out though that will definately add more to the time curve.

Thanks again,
