The 'Mainframe challenge' forum is, for setting problems you already know the answer to and seeing how well others answer it. Please post all your help related questions in the right forum

In HOGAN COBOL who do you call to do the following:

1). Read a file?
---->The answer is PEM or the Processing Environment Manager.

2). Write a file?
---->The answer is PEM or the Processing Environment Manager.


3). Issue a condition code?
---->The answer is no one, when a condtion code is issued the program abends listing the predefined condtion for the cause of the abend.


In HOGAN COBOL instead of defining input and output files in the program, they are defined in the CICS region as Read and/or Write activities under the HOGAN Umbrella. Therefore, when you want to read and/or write simply call PEM and he will handle the rest.

Below is a HOGAN COBOL program that has READ, WRITE & CONDITION CODES.

Note the condition codes are only issued when PEM does not return with a good result after performing the desired action otherwise processing continues and the program ends normally.


Code:

       IDENTIFICATION DIVISION.
       PROGRAM-ID. X99999.
       AUTHOR.

Kolusu,

I think the author is Bernie Hogan, from my understanding the UMBRELLA system was developed in 1978 and is primarily used in the banking industry.

I do not have a way of providing any documentation as it is all on our book manager system therefore I cannot provide a link. CSC in Dallas provides support for all of the institutions who currently operate under the Hogan Umbrella, they also provide training for new HOGAN programmers.

I attended their training about 8 years ago in Dallas.

Here are some links that will provide some general information about HOGAN COBOL.
