[DDI-SRG] [Fwd: Re: [DDI 3.0 0000007]: PhysicalRecordSegment in GrossRecordStructure shoudl be optional]

[Wendy Thomas]

An SPSS file is a proprietary structure not a fixed format or delimited 
file. We currently have no BasicRecordLayout for proprietary files. the 
start of one has been suggested on the spreadsheet in item 6 and J will be 
sending something out on that next week for additional discussion.
