In general, Classic Pascal has required that all bounds be specified 
at compile-time.

The new Extended Pascal Standard does allow bounds to be specified
at run-time.  You can say

    TYPE
	matrix( size : Integer ) = ARRAY [1..size,1..size] OF REAL;

    VAR
	x : maxtrix( run-time-expression );


The only compiler that I know of that has implemented this feature
from Extended Pascal is VAX Pascal version 4.0.
