Chapter 5 Using Asssembler
78 Command Options
5.3.4 Program Generation Options
Functional Description
This option causes the assembler to include in the relocatable object file information for use in
debugging at the source code level.
This information includes the following:
• Names and addresses of variables
• Detailed information on variables
• Correspondences between line numbers and code addresses
With this information, debugging is much easier since the user can specify variables by name instead of
by address.
NOTE: This option must also be specified when linking. If the g option is not specified for
either the assembler or linker, debug information will not be output to the
executable format file (.EX).
NOTE: If the number of lines per source file exceeds 65535, some part of the debug
information will not be output. Make sure when you debug programs, one source
file can contain up to 65535 lines. Divide a file with more than 65535 lines to
avoid errors. Note that the file names or line numbers in error messages will not
be shown if the linker generates error or warning messages after the line 65535.
Rules of Use
This option is specified with the hyphen (-) option specification character, followed by the lower-case
letter 'g'.
