OS-9 Pascal conforms pretty closely to ISO Pascal as described in Jensen
and Wirth's Pascal User Manual and Report.  I used it for my first
undergraduate CS courses in 1985 and 1986. If it is primitve, it is
because that is the way the standard was. There are a couple things that
it doesn't support (packed arrays for instance), but generally they are
of little to no use in the OS-9 environment (packed arrays, if
implemented would be identical to "normal" arrays on the CoCo).
