Ed and Others, Thanks for the lesson in colloquial jargon.
Obviously, I have been schlepping all these many years and did not realize it. Just a final note: MS Word 97's spell checker recognizes both "schlep" and "schlepping."

It's Yiddish, meaning to haul, to drag, to sweat, to expend considerable energy with little reward and no respect. It's five steps forward and four steps back, plus you stub your toe. And there's a rock in your shoe. And you just might be developing a blister. Sisyphus was a schlepper. Yes, it's certainly a military term, although each service and era assigns a new name to it. But, now that I think about it, maybe a trip to the parking lot doesn't quite measure up to schlepping. ;-) Ed ------------------------ From: "Knighten, James L" <[email protected]> Subject: RE: Precompliance Testing Date: Mon, 3 May 1999 15:37:35 -0700 To: [email protected], 'Brent DeWitt' <[email protected]>, Allen Tudor <[email protected]>, [email protected], Gary McInturff <[email protected]> > Ed, > > I'm not familiar with the verb "to schlep." > > Is this a specialized technical term, perhaps particular to EMC or to the > military arena? > > Jim > > Dr. Jim Knighten e-mail: [email protected] > <mailto:[email protected]> > Senior Consulting Engineer > NCR > 17095 Via del Campo > San Diego, CA 92127 http://www.ncr.com <http://www.ncr.com> > Tel: 619-485-2537 > Fax: 619-485-3788 > > > -----Original Message----- > From: [email protected] [SMTP:[email protected]] > Sent: Monday, May 03, 1999 2:38 PM > To: 'Brent DeWitt'; Allen Tudor; [email protected]; Gary > McInturff > Subject: RE: Precompliance Testing > > The roof alternative has been done more than a few times.
