The original Colossal Cave Adventure consists basically of a
Fortran source file and a textual data file. These files would
often travel from one installation to another via paper printouts:
printed out at one site, typed in by hand at another.

The lines of WOOD0350’s Fortran source (intentionally or not)
never exceed 80 columns regardless of your tab stop.
But the data file fits within 80 columns only with a tab stop of four.
With an eight-space tab stop, four lines of the data file exceed 80 columns:

A deep-dive into a historical data corruption bug in the original Colossal Cave Adventure game. When the data file was printed and retyped at different sites, lines exceeding 80 columns with an 8-space tab stop got truncated, causing specific gameplay bugs: the Cobble Crawl losing its light, Witt's End losing its DOWN exit, and maze hint counter resets. Evidence from multiple historical versions (ANON0501, OSKA0501, MCDO0551, ROBE0665, LONG0751) is traced to show how truncated paper printouts propagated these bugs through the game's lineage.
