Each file table has offsets for where the line numbers, local
strings, local symbols, and procedure table starts from within the
- global tables, and the indexs are reset to 0 for each of those
+ global tables, and the indices are reset to 0 for each of those
tables for the file.
The procedure table contains the binary equivalents of the .ent
