How to add 20 Digits number in Cobol?
For Ex:Suppose I have two numbers 10000000000000000000
and 10000000000000000000 and I want to add it.How can I do it in cobol?
SInce Max Allowable Pic Clause in cobol is 9(18).How It can be done? |

you could use the ARITH(EXTEND) option.
you can find info in COBOL documentation. |

This is true only if ARITH(EXTEND) isn't being used. |

You can pass the arith(extend) compiler option thru parm parameter. Ohterwise you can code like below....
Process arith(extend),
Identification division.

| If you are restricted to an old compiler where the ARITH(EXTEND) option was not yet available, you could split the 20-digit numbers into "left" and "right" halves, add the right halves together, carry (if necessary) to the left halves, add the left halves, then concatenate the halves back together into your 20-digit number. Of course, since you are limited to 18 digits, you'd need to define that 20-digit number as alphanumeric. |

If you have an absurdly old compiler and you want to have a number with 20 significant digits, you can't, as ARITH(EXTEND) which allows for up to 31 digits is not supported.
So you have to split the number into two parts, neither of which exceeds 18 digits.
The likelihood of this situation arising is extremely limited, so I'll leave it at that. |
