It took me a few days to locate the manuals and check the date
on the PASCAL.SAV file.  The manual has PASCAL-2 V2.1D
and the file is 397 blocks with a date of 19-Sep-1985.  There is
also a PASCAL.OBJ file with the libraries.

For some reason, there must have been some development after
1999, so there is also a patched file which provides the correct
date on the listing file which is generated.  The patch is less than
a dozen extra instructions and consists of a subroutine call which
checks the 2 high order bits of the date to determine the correct
year under RT-11.  There are no corresponding patches for the
libraries at this time.

If anyone is able to sort out the IP aspects, I can make the files
available along with the manuals which are in poor condition.
