The reason pascal is so easy to work with is that each phase of a program is separate... you have your Units, then types, variables, functions, procedures, and blocks of code all separate
making a mish-mash of variable declarations and code would make it quite easy to inadvertently add a new variable similar, but not identical to an existing one, for example.
It's good that procedures and functions in pascal are different. One of the big problems with C is that you can leave function results dangling, which works against the clean separation of purposes... procedures have side effects, functions tend not to (but can).
One of the most clever things in pascal is assignments := are very hard to confuse with tests for equality =. You're not likely to accidentally confuse them.
