ARITH
ARITH
affects the maximum number of digits that you can code for integers, and the
number of digits used in fixed-point intermediate results.

>>-ARITH(-+-EXTEND-+-)-----------------------------------------><
|
Default is: ARITH(COMPAT)
Abbreviations are: AR(C), AR(E)
When you specify ARITH(EXTEND):
- The maximum number of digit positions that you can specify in the PICTURE
clause for packed-decimal, external-decimal, and numeric-edited
data items is raised from 18 to 31.
- The maximum number of digits that you can specify in a fixed-point numeric
literal is raised from 18 to 31. You can use numeric literals with large
precision anywhere that numeric literals are currently allowed, including:
- Operands of PROCEDURE DIVISION statements
- VALUE clauses (for numeric data items with large-precision PICTURE)
- Condition-name values (on numeric data items with large-precision PICTURE)
- The maximum number of digits that you can specify in the arguments to NUMVAL
and NUMVAL-C is raised from 18 to 31.
- The maximum value of the integer argument to the FACTORIAL
function is 29.
- Intermediate results in arithmetic statements use extended mode.
When you specify ARITH(COMPAT):
- The maximum number of digit positions in the PICTURE clause for
packed-decimal, external-decimal, and numeric-edited data items
is 18.
- The maximum number of digits in a fixed-point numeric literal is 18.
- The maximum number of digits in the arguments to NUMVAL and NUMVAL-C
is 18.
- The maximum value of the integer argument to the FACTORIAL
function is 28.
- Intermediate results in arithmetic statements use compatibility mode.
