Hello Barbara,

thank You for Your contribution, I am afraid it'll take me some time to process 
it in my mind to extract the answer to my initial question.

Just a note to

I undestand that if I MORE often pass fixed-length field, VARYING is still 
possible but not very good because parameters do not match(?) and RPG must 
handle it. 
Does it mean that my idea of having a single prototype for String constructor 
is basically wrong ? I have intended the prototype available to the RPG 
programmers here (knowledge of Java support in RPG has not spread here yet) and 
I do not know which parameter passing method will prevail.

Best regards
Otto Steffan
