Hello, Thomas; hello, GPC-list!

According to Thomas Dunbar:

Yes, one can.  The correct assignment reads

  ch:= s [ 2 ];

I think, this is Standard Pascal, nothing special.  At least, it is
common between UCSD, Borland and GNU Pascal.

In the above sense, a string actually *is* a packed array of char.

Yours,
