As Jon says, CONST is a convention; you can, with some work, shoot yourself in the foot. I use CONST mainly to allow expressions or literals to be passed to the called procedure.

The only way to be absolutely sure your parameters can't be updated is to use VALUE. The primary limitation of VALUE is that you can't use VALUE for a procedure defined as EXTPGM (that is, when calling another program).
