RE: Prototyping a constructor of java String class

You could get the same results without VARYING if you use the %TRIMR()
built-in function.

Hello Bob,

neither do I, but VARYING works perfect in my programs. Not having this
keyword in the prototype, the string object gets full content of a char
parameter including any trailing blanks. getBytes method returning Varying
character value has exhibited it to me (hope I did not make a mistake in my
conclusions). On the other hand having this keyword on, the string object
gets current length of parameter.
I am always been facing the problem that when I declare the size of char
parameter to N in the prototype, it occurs afterwards that I would need to
create another longer string object. Hence my question if 65535 size can be
specified.

regards
Otto Steffan

I'm no Java expert, but I think VARYING is not applicable to the prototype.
Also if you use CONST and OPTIONS(*VARSIZE) you may pass a value of any
length and the compiler will (probably) not generate a temporary
variable--it'll pass the original value by reference. Of course if you
specify a literal for the parameter (as in your example) then the compiler
will (probably) generate a temp variable.
