 Subject: Cobol and Functions
Message:
Hi,
I'm initialize in world of Cobol, and I would like some things about Cobol.
I have some experience in C, and I use frequent functions.
Cobol also have Functions?
Example in C:
int sum(int x, int y)
{
int z = x + y;
return z;
}
Is possible in Cobol?
Regards
//Graveyard

Cobol has a set of prewritten "Intrinsic Functions".
See a manual (available online) for syntax. Or write separate mini programs and "CALL" them from your program. Use dynamic linkage.
CALL "MYFUNCTION" USING parm1 parm2 parm3 ...
The Intrinsic Functions (if they'll fit) are:

The 2002 COBOL standard includes user-defined functions.
Somewhat like you illustrated but more elegant. However, not
all implementations have them.
