Rather than proving it out myself, it's so much easier to ask if anyone has run into this before. While researching a bug, I found a program that chains to a file using a 3-field key list. BUT - the 2nd and 3rd fields are "wrong" (defined as alpha in the key list but numeric in the file). Seems like the result is as tho CHAIN was done using only the 1st field. Is that what actually happens ?
Just because I want it to be true doesn't mean it is.
