[tex-k] Subroutine calls in Pascal (in DVItype)

[Igor Liferenko]

Hi,

In §27 of DVItype there is this text:

    ... in order to minimize the overhead for subroutine calls.

As far as I understand, `subroutine' is a synonym for `function'.
But `get_byte' is a function. So, how does using a function
minimize overhead for a function call?

Somebody please explain.

Regards,
Igor
