38% have ambiguous names (multiple versions exist; 1107 lexfiles).

Only 2 non-identical lexfiles have identical checksums (ESCAPELX and LEXLX95).

Only 7 lexfiles violate HP's official ID/token allocations:
    SKEYLEX and INVERSE violate only a single allocated ID/token,
    but *all* the keywords in CLKCALFN, KOO, PLOT61, PLOT71LX, and RMM61 are in violation.
