Symbol File In Zilog Symbol Format
A symbol file in the Zilog symbol format is generated when the user specifies the absolute
link mode (-a linker option). It is in the standard Zilog symbol format as shown inFigure 3-3,
which follows. In each row, the first column lists the symbol name, second column lists the
attribute of the symbol (“I” stands for internal symbol, “N” stands for local symbol, and “X”
stands for public symbol), and the third column provides the value of the symbol expressed
as four hexadecimal bytes.

The librarian performs the operation specified in the options on the named library using the
named member files. Libraries conventionally have an extension of .lib and library mem-
bers have an extension of .o.
