Normally it should not be necessary to reset static variables.
But sometimes there is a need to do so as dennis pointed out for example to
reset totals.

In this situations I use an optional parameter (simply an indicator). If
this parameter is passed, the static variables first get initialized.
At the first call, I pass the optional parameter (with *ON) and for all
subsequent the parameter is either not passed or passed with *OFF.

Betreff: RE: Correct use of STATIC variables

I think the point of STATIC variables is, you DON'T initialize them
between program calls. At least, not according to this description from
the RPG Reference on static variables. I mean, how do you initialize
something that is not visible outside of its context, such as a
procedure?

Upon occasion I will have a procedure that needs to know if it needs to be
"reset." Maybe it's accumulating some total for groups of data or ...

For example, if one parameter is a flag that is passed to indicate "First
call from this entity" (whatever that entity may be). When the procedure
sees that flag is set, it can do its re-initialization.

Is this what the OP had in mind?
