Core Modules (from Phase-III Macro System)

Core Modules perform input transformation, calculations and output transformation.

Name	Purpose	Algorithm
%TOP_FILT()	Generate standard data structure for processing	Read from source dataset or view and perform filter and select operations
%ROW_FILT()	Generate context dependant standard data structure	Read from source dataset or view and perform filter and select operations with respect to a given context variable‘s value.
%TOP_FREQ()	Calculate PCTs and counts from standard data	Read output from *_filt module and perform calculations of frequencies and counts.
%ROW_FREQ()	Calculate PCTs/counts from context dependant standard data	Read output from *_filt module and perform calculations of frequencies and counts allowing weighting with percentages from context variable.
%ROW_UNIV()	Calculate univariate statistics from context dependant standard data	Read output from *_filt module and perform calculations of univariate statistics according to given list with respect to their sequence.
%TOP_OUTC()	Format categorial values according to table shells	Read output from *_freq module and generate an output file with character formatted columns, totals, header and indentation.
%ROW_OUTC()	Format categorial values from context dependant standard data	Read output from *_freq module and generate an output file with character formatted columns, indentation and weighted percentages. Add counts and percentages from context variable as headline.
%ROW_OUTV()	Format continuous values from context dependant standard data	Read output from *_univ module and generate an output file with character formatted columns, stat labels and header.
