You can see the exact differences at www.standardpascal.org
UCSD started as a subset of Wirth's Pascal. This makes sense if you
realize that UCSD came from the P series compiler ****ting kit from
Wirth, which was deliberately subsetted from full Pascal. Wirth and
company thought it would make the ****ting of Pascal go faster if you
left some of the more complex details out.
According to the later manuals on UCSD they did put some of the details
of original Pascal back into UCSD (but not all of them).
The main thing you will see carried over from UCSD to Turbo is the
string handling. Not so with the file handling, the convention of
"assign(f, n)" was invented with Turbo.
