Gods Of COBOL

Joe Woodbury

My eyes keep glazing over while trying to read this. I tried sending it through Babel Fish, but it didn't do any good. I'll just guess that it means:

int main()
{
puts("Hello World");
}

As far as I can tell, it means that the chances of you using COBOL to stop the nuclear countdown in 24 is going to be slim. Jack Bauer: "Dammit Chloe. I need aerial surveilance now." Chloe: "I'm trying Jack. I'm still only halfway through the declaration section."

Might be worthwhile running it through a COBOL to C translator. Then maybe you can make sense of the C code.

Pic 9(04) COMP-5 is a 4 byte numeric stored in machine independent format Essentially, those two lines redefine the space originally defined by MEMORY-AREA-ONE into two blocks of unsigned 16-bit integers. I cannot recall what the INDEXED allows you to do anymore ... Not sure any of that helps you ... [edit] You might also considering hitting up the COBOL User Groups[^] for help with this, and/or other COBOL related issues you might have. Just a thought.

Hi Chris, you are aware there are a couple of .NET COBOL compilers around? you might be lucky and have a look at the IL your source generates; and reflector might be willing to show you equivalent C# or VB.NET code. And maybe you don't need to translate it after all, just run it... :)

4 bytes left over Maybe the 4 extra bytes are for the array index variables (K01-1-X & K02-1-X)

01 MEMORY-AREA-ONE PIC X(2816).
01 REDEFINES MEMORY-AREA-ONE.
05 K01-1 OCCURS 37 TIMES
INDEXED BY K01-1-X PIC 9(04) COMP-5.
05 K02-1 OCCURS 1369 TIMES
INDEXED BY K02-1-X PIC 9(04) COMP-5.

maybe becomes :confused:

union {
{
PIC MEMORY-AREA-ONE X[2816];
struct {
PIC K01-1-X;
PIC K01-1[37];
PIC K02-1-X;
PIC K02-1[1369];
} COMP-5
};

'leftover bytes' feels stupid

COBOL programmers were never known to be sticklers for programming best practices. COBOL, like VB, allows non-programmers to think they can program. I have many years of experience in technical support (we programmed in assembler on IBM mainframes) supporting COBOL shops, and I have the scars to prove it.

i think that defines an iterator/pointer that's initialized to the start of the subgroup.

Allocate a block of memory 2816 bytes in size and fill with 'X'. Name the block of memory 'MEMORY-AREA-ONE'.

Reallocate the array for a different purpose. K01-1 is an array that contains 37 elements. The index to the array is K01-1-X. Each element is a 4-byte numeric. 'PIC 9(04)' Each element is stored as a 2's complement big-endian number in machine-dependant format. 'COMP-5' When I say big-endian I mean that when the number is displayed it will be displayed as 4 digits from left to right with most significant to least significant order. Whether it's big-endian in memory depends on the implementation. K02-1 is a 1369 element array with similar properties. K01-1-X and K02-1-X are the variables used to index the arrays. Each one belongs to it's respective array and can't be used for the other one. p-code example: for K01-1-X in {1 .. 37} do something with K01-1[K01-1-X]

Machine-dependent format if I'm not mistaken. COMP-4 is machine independent.

how can they be 4 byte integers ? that's twice the size of the MEMORY-AREA-ONE's 2816 bytes. (37 + 1369) * 4 = 5624 i'm thinking the 4 is the number of places allowed for the value. 9(4) is a 4 digit integer (0-9999) ? you can fit that in a two byte integer, which would fit in the 2816 bytes. make sense ?

yeah I updated my post after I realized I put the wrong info in it. 4 byte 'numeric'. the numeric is stored in memory as a 2's complement number, big-endian and machine-dependent format. So 37 * 2 + 2 for the first array, and 1369 * 2 + 2 for the second array. ==> 76 + 2740 = 2816 bytes.
