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.

Table 3-2Options That Can Be Passed in Program Text

Option	Description
b	Uses buffering of the file output.
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.
p	Uses statement limit counting (different from command-line p1). See
	stlimit in the Pascal 4.0 Reference Manual.
