Original source and ERB (ZORKERB I)

Source

ZORKERB I is based on the ZIL source of historicalsource/zork1 at commit 97b7b3d68c075dd9af7da499c3e9690ada3471fd, available at https://github.com/historicalsource/zork1/tree/97b7b3d68c075dd9af7da499c3e9690ada3471fd.

The original story used for comparisons is COMPILED/zork1.z3 of the same commit (Release 119 / Serial 880429, SHA-256 37084966477dff679282de42974b2077156b1bd68fad92a65d4ea94d8eb64d79).

Mapping per ROUTINE

In the development environment, every ROUTINE of the source is listed with where it is implemented in the port, whether its strings are present, whether those strings were observed in comparisons with the original, and whether the source references it.

Status	Count	Meaning
VERIFIED	175	A comparison with the original recorded the routine's text, and the port's response was equal
IMPLEMENTED	265	The strings are in the port, but no recorded comparison has produced them yet (includes routines without strings)
UNREFERENCED	1	Not used anywhere in the source (UNTIE-FROM: no syntax line names it)
GAP	0	Strings found neither in the port nor among recorded reasons

GAP 0 means that every string of the source is in the port or has a recorded reason for being unreachable. It does not mean that every branch has been verified; see Verification.

Branches that are never reached

The source contains branches that Zork I never uses:

• branches for Zork II and III (selected by ZORK-NUMBER);
• commented-out sections;
• DEBUG output;
• flags that no Zork I object has, such as WEARBIT.

These are not ported.
