I was trying to use the SUB Arithmetic operator in the INREC statement and am not able to get the ouput in the desired 'BI' format. When I do not give BI it gives me the results in M0 format.When I try to do BI it does not return me the sign (-) for negative numbers. Please help. I have attached my sort statements below.


Code:

INREC FIELDS=(1,11,
              22,10,             
              148,4,BI,SUB,152,4,BI,BI,LENGTH=4)
SORT FIELDS=(1,21,CH,A)               
INCLUDE COND=(((146,2,CH,EQ,C'D1',OR,
               146,2,CH,EQ,C'D2',OR, 
               146,2,CH,EQ,C'D3'),AND,
               66,2,CH,EQ,X'0065'),OR,
              ((146,2,CH,NE,C'D1',AND,
               146,2,CH,NE,C'D2',AND,
               146,2,CH,NE,C'D3'),AND,
               66,2,CH,EQ,X'0064'))

Pknair,

In what format do you want to store the result from the subtraction ?

BI is strictly for positive binary numbers (e.g. X'FFFF' is 65535). FI is for positive and negative binary numbers (e.g. X'FFFF' is -1).

It doesn't make any sense to say

since BI values are unsigned (only positive).

Thank you Kolusu and Frank. I understood my mistake and changed BI to FI.
