# TAGGED SUMMARY — compiler outline v1 [tag: compiler-outline-v1]

One-page snapshot. Details in `00-overview.md` .. `70-rename-plan.md`.

## What

Turbo Modula-2 compiler decompiles and runs, but
`decompiled/COMPILER/` identifiers are `procN/globalN`.
This folder restores the map without touching upstream sources
(upstream dirs are git-ignored).

## Map

* Resident: `Compiler` (symbol descriptor + predefs) + `Scanner`
  (128B window, `GetSym/Accept/Expect`) + `SymTab` (scopes, `.SYM`
  import/export) + `Errors` (`ERRMSGS.OVR`, `Edit/Quit`, rollback) +
  `CodeGen` (MCode emit, 2KB window, `OpenFix/CloseFix`).
* Transient (`Loader.Call`): `COMPILE = Pass1` (decls/types/`WriteSym`) +
  `Statemen` (`STMT` dispatch 121..130, `FOR/CASE/IF/...`) +
  `Express` (`EXPRES`, designators, const-fold, std-proc expand) +
  `GENZ80` (native, later).
* Drivers: `C.MOD M2C`, `Scanner.Compile`, `ComLine`.

## Key renames (proposed, `~` = to confirm by recompile)

`Compiler`: `PROC3/4/5/6/7 InsertIdent/DeclConst/DeclStdProc/DeclProc/DeclFunc`,
`PROC14/16/17/18 DeclarePredefTypes/DeclareStdNames/DeclareSYSTEM/DeclareSTORAGE`,
`PROC1 InitCompiler`, `GETINP OpenSourceOutput`.
`Scanner`: `proc1/2/4/8 GetSym/NextChar/Accept/Expect`, `proc30 Compile`.
`CodeGen`: `Emit1/2/Word/String`, `Peek/Poke`, `FlushWindow/SeekWindow`,
`OpenFix/CloseFix/InsertFix`.
`SymTab`: `Find/EnterModule`, `LookupChain`, `ImportAll`, `SaveSym`.
`Errors`: `Error/Msg/Fatal/FindFile/EditQuit/RollbackScope/Expected/TypeMismatch`.
Frontend: `ParseType/ParseRecord/ParseFormals/ParseProcedure/ParseMain`,
`ParseStatement/ParseStatSeq/ParseCASE/ParseFOR`,
`ParseExpression/ParseSimpleExpr/FoldConstOp`.
