① The whole original system
44 programs · 22,904 lines of mainframe COBOL.
The stats page percentages measure THIS box — nothing else.
1 program fully translated + byte-verified (the pilot) — the 1.6% (P3)
+10 programs already compile on Linux — together the 13.8% (P2)
3 need small copybook fixes
25 CICS screen programs (74.7%) — the big block, awaiting the screen-rewrite route
5 DB2/IMS — awaiting the database port
% cannot be high yet: three-quarters of the system is CICS screens,
and CICS does not exist on Linux — that layer must be rewritten, not recompiled.
the pilot went through the factory →
② The translated pilot — CBACT01C
The one program that finished the whole journey. It exists twice:
P2 · COBOL on Linux (GnuCOBOL)
P3 · PHP written by Gemini
Both read the same account data (50 records) and write the
same output file. The oracle byte-compares them: 5,350 bytes, identical ✅
this box IS counted in the % — it is the green + purple sliver of box ①
what you can touch below →
③ This demo page
▶ Run batch / ⚖ Verify buttons → run box ② for real — translated code, counted in the %
🖥 green screens (menus 1·2·3) → rebuilt new small screens — a preview of the
end state for the 25 CICS programs. New code, so they add 0%
but they show real translated results: the screens read the same data files,
and Posting Summary (3) displays the output file box ② wrote
the interface proves the METHOD · the % counts how much of box ①
has been through it: P2 13.8% · P3 1.6%
