New Features for HP Pascal
by Chip Chapin--Data & Languages Division/CLL
This new version of HP Pascal/XL provides greater compatibility with the
current versions of HP Pascal/UX, and HP 9000/300 Pascal. It also offers
improved support for the XDB symbolic debugger, procedure-per-SOM, and
new predefined procedures to ease the porting of SPL programs from MPE
V/E. Detailed information on these new features (listed below) may be
found in the HP Pascal/XL Reference Manual (P/N 31502-60005) and HP
Pascal/XL Programmer's Guide (P/N 31502-60006).

source compatibility with HP 9000/300 Pascal:
1. The $SEARCH compiler option now works with archive files, and can
extend across multiple source lines.
2. The $PAGEWIDTH, $WARN, and $SYSPROG compiler options have been
implemented.
3. I/O to $STDLIST is now unbuffered.
4. It is now allowable to take the ORD of a pointer type.

The following features have also been added to this new version of HP
Pascal/XL:
1. It is now possible to put the code generated for each Pascal
procedure into a separate SOM.
2. Four new predefined procedures are available, primarily to
simplify the porting of SPL code to Pascal.
3. Pascal now supports a 16 bit logical data type.
4. Pascal and the XDB symbolic debugger now offer support for
symbolic debugging of conformant arrays and procedure variables.
5. IEEE floating point conformance.
6. Limited support for international characters in Pascal source code
is provided.
7. Arithmetic overflow checking may be done on a per-statement basis.
