B- 3
setenv PASXDATA n
or the command:
PASXDATA= n
export PASXDATA
Maxpos The call maxpos(f) returns maxint , regardless of
f .
Open options The third parameter of the predefined file-opening
procedures append, associate, open, read, reset,
rewrite, and write . It is optional for all but
associate , for which it must have one of the
values listed in "Associate Procedure" .
Ord At the STANDARD_LEVEL 'EXT_MODCAL' ord allows
short pointers as arguments.
Output The standard program parameter and textfile output
is stdout .
Stderr
The standard program parameter and textfile stderr
is the HP-UX file stderr .
System intrinsic file ../../sys/pub/sysintr
System default module /usr/lib/paslib
library
Temporary files
If the environment variable TMPDIR is defined (as
a path to a directory to hold temporary files),
temporary files are placed in that directory;
otherwise, temporary files are created in the
directory /usr/tmp . (See the standard HP-UX entry
point tempdir(2) .)
Write If the file being written is a terminal, the
output is unbuffered. This means that write to a
terminal has the same behavior as prompt .
HP-UX Extensions
HP-UX extensions are available only to programs that are compiled by the
HP Pascal compiler running on the HP-UX operating system. The programs
themselves must also run on the HP-UX operating system. The HP-UX
extensions are:
* Access to special global variables through the EXTERNAL directive.
* The predefined function get_alignment , which returns the alignment
requirement of a given type or variable.
* The predefined function statement_number , which returns the
statement number of the statement that calls it.
Accessing Special Global Variables
The global variable errno is special in that a program can access it
through the EXTERNAL directive.
Example
$EXTERNAL$
