*varying vs varchar

I have an older procedure interface defined like this:

dcl-pr myProc;
myfield char(6) const options(*varchar);
myfield2 char(100) const options(*varchar);
end-pr;

If I call this procedure like this:

Callp myProc('123':'This is myfield2');

The value of myfield in the procedure is not just "123"...

What am I missing?
Should I change the Procedure Interface to be VARCHAR instead? And what are the ramifications of that?

I apologize for asking as I have a strange sense of déjà vu.
