The first lines of the file your AI will read, exactly as delivered. Nothing rewritten for the page.
You are a Socratic COBOL tutor, and your learner has inherited a batch program on z/OS and needs to read it before changing it. You have been activated to teach PIC clauses, COMP-3, copybooks and FILE STATUS codes.
// what's inside
New hires on mainframe teams, developers maintaining a bank, insurance or government batch system, and analysts documenting COBOL before a migration.

This AI COBOL tutor is for the mainframe role you have taken, the batch program written in 1994 you inherited, or the team migrating a bank or insurance system off it. Nobody has time to teach you, and the person who wrote the code retired. Paste this file into Claude, ChatGPT or Gemini and you get a tutor aimed at reading and maintaining production code, not at printing Hello World.
It places you by asking what you can already read in the program on your screen. Then the plan follows what the job needs: the four divisions, PIC clauses and what COMP-3 actually stores, level numbers and 88 condition names, copybooks, sequential and VSAM files with their FILE STATUS codes, PERFORM structure, and the JCL that runs the thing. Each lesson is one explanation, one worked example, and a task on code. When your job abends with S0C7 it makes you find which field held non-numeric data before it says anything else.
The file behaves identically in Claude, ChatGPT and Gemini. Single purchase, pay once, keep forever, and you are running in about ninety seconds.
After checkout, the download link lands in your inbox. Save the .txt file anywhere on your device.

The tutor teaches the language on GnuCOBOL, which runs on a laptop, and teaches the mainframe layer separately: JCL, ISPF, SDSF and dataset names. That split matters, because most of what breaks in a real job is the environment, not the syntax. When you get z/OS access it asks what your shop uses and adjusts the examples.
No. It will write a short example program to show a pattern, but on your production code it asks questions and makes you locate things. That is the right shape for this job: on a maintenance team you are judged on whether you can explain what a change does before you make it, not on how fast you can produce lines.
It covers the language properly, then the surrounding pieces at the level a maintainer needs: JCL job, EXEC and DD statements, embedded SQL and the precompiler, and what a CICS transaction is versus a batch step. It says clearly when a detail is shop specific, such as dataset naming or scheduling, and tells you to ask a colleague.
