2.5.3 Link options

This section explains options for the link phase.

Caution about options are shown below.

-	Uppercase characters and lowercase characters are not distinguished for options.

-	Uppercase characters in options and parameters indicate that they can be specified as abbreviations for options and parameters. The characters after the uppercase characters can be omitted.

Example

For example, -FOrm=Absolute can be specified as follows.
-fo=a
-fo=abs
-for=absolu

-	When a file name is specified as a parameter, "(" and ")" cannot be used.

-	When link options are specified for the ccrh command, the -Xlk_option option must be used.

The types and explanations for options are shown below.
