Others have pointed out that the %len of a fixed length field is always the
defined size.  They do call it fixed length for a reason! <grin>

But just wanted to point out that you will run into other problems if you
are indeed calling this from the command line as you say.

You'll run into the well know problem of passing variables > 32 char's from
a command line.  CL is only passing you 32 characters but the RPG program
expects 100.  Notice the 'yada' followed by 28 blanks, followed by 68 x'00'.

This is discussed in the FAQ.  If you need more help, you might want to move
the message to the RPG list.
