Mainframe, MVS and zOS Discussion

Hi,

I have a rather trivial question I think. A PD is called as PD because the way the number is stored in the memory, it is same for binary values too. But why ZD fields are called as zoned decimal. They are "displayable fields" so where the word "zone" came out from?

William:

I'm testing a change and was thinking to add an aaditional variable for testing for future, left in the program as a comment. The value of the variable would change frequently for testing.

Robert:

Thanks. I shall check if I can change the copy book and keep the new variable as comment ...

Hi,

I've a COPYBOOK like this -

01 COPYBK-IND.
05 COPYBK-CURRENCY.
10 COPYBK-STATE-CURRENCY PIC X(01).
88 COPYBK-CURR-A VALUE 'A'.
88 COPYBK-CURR-B VALUE 'B'.
88 COPYBK-CURR-C VALUE 'C'.
05 COPYBK-OTHER
10.....


Now I need to add a 88 level variable without changing the copybook ...

I'm also from India.
