The Pascal Compiler 25

The –b option on the command-line turns on block-buffering with a block size

of 1,024. You cannot turn off buffering from the command-line.

If you give the –b option in a comment in the program, you can turn off

buffering or turn on block buffering. The valid values are:

Any number greater than 2 (for example, {$b5}) is treated as {$b2}. You can

only use this option in the main program. The block buffering value in effect

at the end of the main program is used for the entire program.

-bsdmalloc

(Solaris 1.x only) The -bsdmalloc option speciﬁes faster malloc and uses the

more efﬁcient malloc from the library, libbsdmalloc.a. This option also

causes the ﬂags, -u _malloc /lib/libbsdmalloc.a, to be passed to the

linker.

–C

The –C option enables runtime checks that veriﬁes that:

• Subscripts and subranges are in range.

• The number of lines written to output does not exceed the number set by

the linelimit procedure. (See the Pascal 4.0 Reference Manual for

information on linelimit.)

• Overﬂow, underﬂow, and divide-by-zero do not exist.

• The assert statement is correct. (See the Pascal 4.0 Reference Manual for

information on assert.)

If you do not specify –C, most runtime checks are disabled, and pc treats the

assert statement as a comment and never uses calls to the linelimit

procedure to halt the program. However, divide-by-zero checks are always

made.

The –V0 and –V1 options implicitly turn on –C.

{$b0} No buffering

{$b1} Line buffering

{$b2} Block buffering. The block size is 1,024.
