Option-Passing on the Command-Line
To pass an option on the command-line, use a dash (
-
) followed by the option
name. In some cases, you must supply additional information, such as a file
name. For example, this command activates the listing option
-l
, which is off
by default:
hostname% pc -l rmc.p
The following command causes the generated object file to be named
rmc
instead of the default,
a.out
.
hostname% pc -o rmc rmc.p
Option-Passing in the Program Text
Some options can be passed to the compiler in program text as well as on the
command-line. With this facility, you can use different option values for
different parts of a program.
Here are four examples of how options can be passed in program text:
{$P+}
{$H*}
(*$I-*)
{$l+,L-,n+}
Table 3-2 shows the options that can be passed in program text.
