Hello, There is a small bug in the implementation of array's. See the following example program: PROGRAM test(input, output); TYPE RealVectorT(b,e:integer) =ARRAY[b..e] OF Real; RealMatrixT(br,er,bc,ec:integer) =ARRAY[br..er] OF RealVectorT(bc,ec); VAR x:RealMatrixT(1,5,1,5); BEGIN x[1,1]:=0; { error: test.p: In function `pascal_main_program': test.p:10: subscripted object is not an array or string } x[1][1]:=0; { this is O.K. } END. Both implementations of addressing an array element x[1,1] and x[1][1] should be equivalent. In the first case the compiler does not interpret x as an array. The latter version is correctly interpreted and executed. I have used the relase 2.95.2 19991024 of gpc.
