RE: Prototyping a constructor of java String class

Hello Michael,

thank You that You have noticed my issue and spent some time researching it.

Let me gloss some of Your comments.
I have been integrating a quite complex Java application into a core RPG 
application. The java app have plenty of methods and among them are those that 
provide simplified interface based on passing data in a Properties object (see 
java.util.Properties class). I feed the Properties object with the method 
setProperty:
....
setProperty( Dapi_propsIn                 
           : String( 'Psysid' )           
           : String( %char(insysid) ) );  
setProperty( Dapi_propsIn                 
           : String( 'Pforid' )           
           : String( %char(inforid) ) );  
....
and get output data with getProperty:
...
OUSUBTYP  = getBytes( getProperty( Dapi_propsOut       
          : String( %char(iRSRows) + '.Ousubtyp' ) ) );
....
I could have names of parameters in varying variables but it seems of no sense 
in my situation. This way above seems straightforward to me. The definitely 
worse performance of Properties- parameters exchange with java methods does not 
matter (so far).

I once encountered an article on new things in RPG V5R1 (or R2?) by Barbara 
Morris on www.mcpressonline.com where the return value of getBytes method is 
65k varying.
Not having suspected of any side effect (as the prototype is of IBM), I have 
used it with trust and no doubt. Thank You for the warning.
