Bob, Could you please spell it out for us less experienced programmers what is wrong with the last section of code that will bring on the "learning experience". Tks, Glenn
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. -Bob Cozzi www.iSeriesTV.com Ask your Manager to watch iSeriesTV.com
