1.3.3.2 LINK Qualifiers
LINK qualifiers allow you to control various aspects of the link operation such
as modifying linker input and output and invoking the debugging and traceback
facilities.
Table 1–5 summarizes some of the more commonly used LINK qualifiers. Refer to
the OpenVMS Linker Utility Manual for a complete list and explanations of the
LINK qualifiers or invoke the online HELP facility for the LINK command at the
OpenVMS Alpha prompt.
Note
Brackets ( [ ] ) indicate that the enclosed item is optional. If you specify
