There is no - record structure within the section. The start of the table for a routine - is pointed to by the block record, and the end of the table is signaled by - an escape code. - - A line number table is a sequence of bytes. The default entry contains a line - number delta (-7..+7) in the high 4 bits and a pc delta (0..15) in the low 4 - bits. Special cases, including when one or both of the values is too large - to fit in 4 bits and other special cases are handled through escape entries. - Escape entries are identified by the value 0x8 in the high 4 bits. The low 4 - bits are occupied by a function code. Some escape entries are followed by - additional arguments, which may be bytes, words, or longwords. This data is - not aligned. - - The initial PC offset, file number and line number are zero. Normally, the - table begins with a dst_ln_file escape which establishes the initial file - and line number. All PC deltas are unsigned (thus the table is ordered by - increasing PC); line number deltas are signed.
