It may be tongue in cheek, but while the value of pi will never change, the precision that you need may change, and changing a single precision 3.14159 to a more precise extended precision value is a lot easier if it's only in one place. Besides, while mathematical constants don't change, some

Are not the COBOL compilers smart enough to inline small subroutines? So there is no performance hit whatsoever from making a one-line function into a called subroutine? I know the C/C++ compiler is (whether you declare a method as inline or not, for those of you who are C/C++ people). Charles

The primary purpose of the DATA statement is to give names to constants; instead of referring to pi as 3.141592653589793 at every appearance, the variable PI can be given that value with a DATA statement and used instead of the longer form of the constant. This also simplifies modifying the
