Flowchart

Parameters

Name	Description
dsn	input dataset name
row, row2	categorial variable name, 2=nested variable
exclude	decode for excluded group from &ROW
weight	Y/N (multiply percentages for &ROW and &ROW2)
col	categorial variable name used for columns
head2	Y/N (block header for nested variable)
indent, indinc	n (number of indent columns and increment for nested variable)
num	n (sequence number of output)
stat	Y/N (column with statistics names)
space	1/2/3 (blank line before or after output and between nesting levels)
struct, struct2	name of reference dataset used for full decode structure, 2=nested variable
condense	var#value (non-distinct variable and true value for &ROW)
misslin2	Y/N (force missing line for nested variable)
