The Pascal Compiler 21

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.

Option Description

C Uses runtime checks (same as t).

calign Uses C data formats.

H Uses check heap pointers.

l Makes a listing.

L Maps identiﬁers and keywords to lowercase.
