Re: Easy question about Character manipulation

It depends on whether they are value parameters or var (-iable) parameters.
Value parameters are in effect assigned their values,

var parameters must be of equivalent types, and type-equivalence in
ISO Pascal is name-equivalence.

When I learned Pascal (not ISO), my understanding was that

type
A = 1 .. 3;

was called a subrange, and defined A as what Ada calls a subtype of Integer. Since

B = 1 .. 3;

was another subtype of the same type (in Ada terms), assignment between them was no problem.
