6.6.1.3 Special Cases



The SCPLCU file is created by summarizing observations from
the SCPIOC, SCPLCA, and HARDVA files.  This poses special
problems with keeping track of sample counts.  There are no
RMF sample data elements in the SCPIOC file, but the counts
of the summarized observations from the SCPLCA and HARDVA
files that are used to create an observation in the SCPLCU
file will be different.  Since each is needed for calculating
derived elements, two separate counts are maintained.

o  LCURSMPD is the sum of all occurrences of DVARSMP found
   during summarization.

o  LCURSMPL is the sum of all occurrences of LCARSMP found
   during summarization.

The derived element code for the SCPLCU file uses the proper
sample count data elements in each of its calculations.
