; an offset inside the preprocessed source to the name of file,
; from which this line was loaded (the name of file is zero-ended
; string).
; When the line was generated by macroinstruction, this field
; contains offset inside the preprocessed source to the
; pascal-style string specifying the name of macroinstruction,
; which generated this line.
.source_name dd ?
; Bits 0-30 contain the number of this line.
; If the highest bit is zeroed, this line was loaded from source.
; If the highest bit is set, this line was generated by
; macroinstruction.
.line_number dd ?
; If the line was loaded from source, this field contains
; the position of the line inside the source file, from which it
; was loaded.
; If line was generated by macroinstruction, this field contains
; the offset of preprocessed line, which invoked the
; macroinstruction. If line was generated by instantaneous macro,
; this field is equal to the next one.
.line_offset dd ?
; If the line was generated by macroinstruction, this field
; contains offset of the preprocessed line inside the definition
; of macro, from which this one was generated.

; are register codes and the second two bytes are
; corresponding scales.
; If the $ address is relocatable, this field contains
; information about section or external symbol, to which
; it is relative - otherwise this field is zero.
; When the highest bit is cleared, the address is
; relative to a section, and the bits 0-30 contain
; the index (starting from 1) in the table of sections.
; When the highest bit is set, the address is relative
; to an external symbol, and the bits 0-30 contain the
; the offset of the name of this symbol in the strings
; table.

; was taking place inside the virtual block, and the
; offset in output file has no meaning here.
; If the bit 1 is set, the line was assembled at the
; point, which was not included in the output file for
; some other reasons (like inside the reserved data at
; the end of section).
