[SOLVED] Calculation based on results of Summary

I am not sure how to do define the CALC column.
See the sample data below

CONTRACT CLASS TYPE AMT CALC
A100 A A -200 0
A100 A B 100 0
B100 A A -100 -100
B100 A B 200 200

If the sum of the CONTRACT AMT is positive th CALC = AMT.
If the sum of the CONTRACT AMT is negative the CALC column = 0

In this example:
- Since Sum Contract A100 Amt = -100 the CALC would be 0
- Since Sum Contract B100 Amt = +100 the CALC would be the amt

A multi-set request is in order here. Try the following example:

FILEDEF DATA DISK DATA.MAS
-RUN
-WRITE DATA FILENAME=DATA, SUFFIX=FIX
-WRITE DATA FIELD=CONTRACT, FORMAT=A4, ACTUAL=A4, $
-WRITE DATA FIELD=CLASS   , FORMAT=A4, ACTUAL=A4, $
-WRITE DATA FIELD=TYPE    , FORMAT=A4, ACTUAL=A4, $
-WRITE DATA FIELD=AMOUNT  , FORMAT=I6, ACTUAL=A6, $

FILEDEF DATA DISK DATA.TXT
-RUN
-WRITE DATA A100   A   A  -200
-WRITE DATA A100   A   B   100
-WRITE DATA B100   A   A  -100
-WRITE DATA B100   A   B   200

TABLE FILE DATA
SUM AMOUNT
BY CONTRACT
SUM AMOUNT
    COMPUTE CALC/I6 = IF C1 LT 0 THEN 0 ELSE AMOUNT;
BY CONTRACT
BY CLASS
BY TYPE
END

Hope this helps ...
