The problem with Pascal is that Standard Pascal is limited (i.e.
structured BASIC for learning), everything else is a hack on top, with
each being incompatible with each other.

If I was you, I would look into interfacing Ada with your Pascal code.
Normally, Pascal passes params left to right (unlike C, which is r-to-
l
due to ...), Ada I would think would pass in a similar manner, might
not
be the same though. If not, might be worth looking into the compiler
to
extend it with Interfaces.Pascal (or GPC) and the param passing
mechanism,
so you can import Pascal procedures/functions as Ada subprograms.

e.g.

procedure Some_GPC_Thingy;
pragma import(Pascal, Some_GPC_Thingy);

Would be better than porting Pascal -> Ada.
