Things You'll Need:
- COBOL Linker
-
Step 1
Read the program specification thoroughly. You need to understand what the software needs to do in order to solve the business problem the specification describes.
-
Step 2
Address all questions and concerns with the systems analyst. Find out the functional requirements in the program specification.
-
Step 3
Identify and resolve logic issues. These issues may cause the program to produce incorrect results.
-
Step 1
Provide the program name, author and date written in the Identification Division of the program. Provide a paragraph that describes the input, output and function of the program.
-
Step 2
Describe the inputs and outputs of the program in the Environment Division of the program. Assign input files to input devices and output files to output devices.
-
Step 3
Name and define all variables the program will use in the Working-Storage Section of the program. Define record layouts for reports in this section if necessary.
-
Step 4
Write the code that solves the business problem. Be sure to follow the outline in the corresponding program specification.
-
Step 1
Run the program code through the compiler, It will check for syntax errors and produce an object module.
-
Step 2
Check the compiler listing for syntax error messages. Then correct any errors.
-
Step 3
Recompile the program. Wait to see the end result.
-
Step 1
Run the program through the linker. Doing this action combines the object module and all subroutine programs into an executable file.
-
Step 2
Check the link-editor listing for syntax error messages. Then correct any errors.
-
Step 3
Recompile the program. Then link-edit it.
