Hi,

Can anyone explain the procedure, how the COMP data can be viewed in a file.
Ex : for Comp-3 we will go for HEX ON and we can view the data in the file.
How the COMP data can be viewed in a file ?

HEX ON will allow you to view it but you will still be seeing the binary value....
Use Window's calculator to convert it from HEX to DECIMAL....

CICS Guy: I got tripped up by this a few weeks back, I had a comp field with a value of FFFFFFFFFFFFFECA. The field was PIC S(9). What is the decimal value?

-310

zero your calculator.

hex mode

enter ffff
minus feca
+ 1
equals

dec mode

That's what I ended up doing, I hadn't had to use the 2's complement since school. It threw me for a second because I took the straight hex value and did the windows calc thing and I got a huge number, but I knew it was a DB2 error. I used the windows calculator -> binary flipped the bits +1.

Hi All,

You can check FIle Aid, instead of complex calculations.....

Addition and subtraction are not complex and File-Aid isn't available in every shop. It's better to know how to do it for cases where the data isn't stored in a file, like when you are tracing a program and watching memory to see a value.
