[DDI-SRG] Questions on GrossRecordStructure

[Wendy Thomas]

that looks like the documentation is wrong. there can be multiple parts to 
a logical record. A logical record is basically one per case.

Once again. when there are multiple part records one or more variables may 
be duplicted in each line.

In the past these have been used for the purposes of check sums and may no 
longer be required. We were initially making sure that we didin't lose 
anything from 2.1.

Feel free to file a bug, but note if it is clearly not required in all 
cases, should be a default for the "simple" files, or should have its 
documentation clarified. I am reluctant to toss something that could be 
handled with a default when the only use cases we have to go on are simple 
files. There's a reason they're called simple...they don't require all the 
ocmplexities.
