RE: CONST vs. VALUE

["Stone, Brad V (TC)" <bvstone@xxxxxxxxxxxxxx>]

And that's why i asked here.  i saw a lot of people in their examples using
CONST.  I have almost always used VALUE.  Mainly so that I don't have to
match field sizes and can pass literals, especially for testing.

Since I never looked into using CONST, I never knew what it did.  

I appreciate everyone's responses!
