This may be slightly off-topic, but I can tell you some facts about
my Stanford Pascal compiler,
which runs
- native on z Mainframe machines (which may count as a RISC machine,
given the instruction set used)
- emulated by Hercules, which is a emulator of z Mainframes
- by emulating P-Code, which is a (sort of) byte code for Pascal ...
the P-Code (which is pure text, portable)
is translated to a byte code representation before execution; static
linking is also done in this stage
Bernd, is the dialect used by that compiler "standard" Pascal, UCSD
Pascal, Turbo-compatible, or?
tnx.
g.
The dialect implemented by the New Stanford Pascal compiler is
"standard" Pascal with some extensions,
for example
- extended const syntax (for structures and arrays etc.)
- support for external procedures (contained in "modules")
- CHAR(n) data type
- string data type
- static definitions
- initializations of variables and statics
- OTHERWISE on CASE
- BREAK, CONTINUE, RETURN
- direct read and write of scalar types (enums)
- with clause on record types
- pointers on variables which are not on the heap
- pointer arithmetic
- many new builtin procedures and functions
A short "language reference" (23 pages), which covers the differences to
"standard" Pascal,
is available from this website: http://bernd-oppolzer.de/job9.htm
see the link on top of the page, just below the picture.
Kind regards
Bernd
