The Vector Pascal compiler has a number of extensions to the ISO standard but also falls short in certain respects:
is a spreadsheet which charts a comparison between Vector Pascal and Turbo on the acceptance test suite, which is largely based on the ISO test suite. Test programs that depend on the ISO model of file i/o or on comparisons of packed arrays of char have been modified to use strings and the Turbo model of I/O.
The columns in the spreadsheet are
Tp7 – Turbo Pascal
Vp – Vector Pascal
Vpt – Vector Pascal compiled with the –NOVPWORDS flag which excludes new Vector Pascal reserved words, this is for backwards compliance with ISO tests
