Gods Of COBOL

Jim Crafton

That's a program fragment? It looks like the results a program run as opposed to actual syntax. Bizarre. Glad I never had to deal with COBOL. Makes FORTRAN look absolutely svelte in comparison!

I'm guessing that is a buffer for a transfer protocol or a binary file format. I had to deal with such things ages ago when I had to interface with a tandem mainframe. (1369+37)*2 = 2812 so I think it is a bunch of 2 byte integers with 4 bytes left over.

yeah, it's amazingly verbose. i have to translate a bunch into C/C++ and i'm learning as i go. but this bit makes no sense to me.

hmm... yeah, i suppose that could be it. the 'leftover bytes' feels stupid and wrong, but maybe i should just get over that... i'll give it a try!

I'd learn it, but... well... Some things just aren't meant to be done without large amounts of illegal drugs, and I'm not into that.

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... :)

Their authors should be flamed, immediately. :rolleyes:

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

maybe becomes :confused:

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.
