Don't get confused. This code will not compile.
Why don't you give it a try..? |

Mainframes operate on EBCDIC codes, not on ASCII.
Adding number to a numeric field which contain alphanumeric data can cause S0C7 (Data Exception).
Arithmatic instructions of mainframes are Packed decimal instructions.
So while adding zoned decimal fields, compiler will generate code for 'packing' the number to packed decimal, add and unack again for display. I this process S0C7 can occur in ADD operation, so avoid doing such additions. |

I have understood your question properly and have answered it in my last post.
| Code: |
01 a pic x(3)
01 b pic x(3) redefine a.
procedure division.
move 'ABC' to a. (as you are redefining, b will contain ABC)
display b.
add 2 to b.
(This 'add' will spawn following:
pack - 'ABC' = x'C1C2C3' will get packed as 123
add 2 to 123 = 125
unpack to display 125 )
display a. 125
display b. |
You WILL get S0C7 when adding in the packed field which is not numeric.
For example, instead of ABC move @#$ to the variable, you will get S0C7. Hope I am clear enough this time. |

| Same S0C7 as the data in the memory is not a numeric data. |

Yes i know that. I have copied the code which was pasted by you.
If you declare it numeric then only code will compile and answer is, it will display 125 in this case.
I have explained that there is a large possibility that you may encounter S0C7 in such case ( Adding number to alphanumeric data, which you are doing).
However there will not be S0C7 in 'this case' because 'ABC' will be packed to 123 numeric and will give numeric result. |
