Remember, %TRIM() is NOT %trimR().
I know a lot (most?) RPG IV programmers use %trim() because of the "I know it
works" mentality. But in the rare case when a variable contains leading blanks,
%trim() will return a completely different value than %trimR().

I strongly agree with the person who implemented %trim(), %trimR(), and %trimL()
in RPG IV that as a developer, you should use the Built-in function that applies
and not generically default back to %trim(). If anything, default to always
using %trimR() and then use %trim() on an exception basis, were applicable.

  myVar = '   Bob Cozzi   ';
  len  = %Len(%trim(myVar));
  lenR = %Len(%trimR(myVar));

After the above is performed, LEN equals 9 and LENR equals 12.
So if you code this:
  myVar = '   Bob Cozzi   ';
  len  = %Len(%trim(myVar));
  myWorkVar = %trim(myVar);
  callp  someCorJavaAPI(myWorkVar : len);

You're going to have a learning experience.

Subject: Re: Java string length

The only way that I know of is to use the getBytes routine to convert the
java string to a readable RPG string and then use the %Len BIF with the
%Trim BIF.

D getBytes        PR         65535    ExtProc(*JAVA:
D                                             'java.lang.String':
D                                             'getBytes')
D                                     Varying

RPGfileName = getBytes(fileNamex);

How to dermine the (string) length of this declaration:

 // File Name object
D fileNamex       S               O   Class(*JAVA:'java.lang.String')
 // trimmed File Name object
D tfileName       S               O   Class(*JAVA:'java.lang.String')

Thanks in advance

Marco
