Suppose your data has a series of attributes that correspond to - say - lines on an order, or lines on a call log, or maybe lines on a time sheet.
You want to display the line number beside the other data.
"LINE" will do the trick assuming that attribute 1 is part of that data.
LINE
001 S
002 0
003 Line
008 F;1;NV
009 R
010 2
If you just need a count of the "lines" referenced by the multi-value data in attribute 1, then "CTR" will do that for you.
The assumption is that there are no null elements in attribute 1.
CTR
001 S
002 0
003 Count
008 F;1;C;#;S
009 R
010 7
