Pascal used var parameters rather than pointers into the stack and supported nested subroutines with lexical scope, limiting them to being passed as downward funargs to ensure safety, and it barely missed requiring tag checks on variant record access (an omission Wirth bitterly lamented). Pascal had pointers, but they were strictly for heap-allocated objects, not var parameters or array iteration. In standard Pascal, array size was part of the array type, so you couldn't write functions that operated on arrays of unknown size, because bounds checking of array accesses would have otherwise required passing an additional length word. That's why the string type in TeX is an index into a humongous string pool array.

I think this illustrates how the philosophy of Pascal differed from that of C.
