I found a few small bugs in your diagrams. 1) Identifier [https://www.getlazarus.org/learn/language/lexical/#identifier] It should look as follows: ┌────────────────────────────────────────────────────────────────────┐ Identifiers >>─── identifier ──┬─ letter ─┬─┬──────────────┬───────────────────>< └─── _ ────┘ ^─┬─ letter ─┬─┘ ├─ digit ──┤ └─── _ ────┘ └─────────────────────────────────────────────────────────────────────┘ Note that identifiers can also start with a <underscore> 2) The Program unit structure [https://www.getlazarus.org/learn/language/lexical/#program_header] Strictly speaking (but mostly not used these days), the PROGRAM syntax can also take a parenthesis with input,output identifiers. eg: program MyUnit (input,output); .... 3) Unit Header [https://www.getlazarus.org/learn/language/lexical/#unit_header] Again, your syntax is incomplete and should look as follows: Unit -> UNIT Ident [HintDirective] ';' I didn't go through the rest in detail, but these are the ones I spotted immediately.
