AW: %Len problem

[Werner Noll <werner.noll@xxxxxxxxx>]

Hi,

according to the RPG manuals, %LEN returns the actual data length for
variable-lenght fields only. Your code would work, if you specify keyword
VARYING for field SndMsg. For non-variable-length fields, you just get the
specified field length.

Regards,
Werner Noll

   What's up with this? Here's the definition of a couple of fields...

   D SndMsg          S            100  
   D SndMsgSize      S             10U 0
   Here's the calc...
    
   C                   Eval      SndMsgSize = %Len(%Trim(SndMsg))
    
   and here's what I see in debug...

   EVAL SndMsgSize                                                        
   SNDMSGSIZE = 000000100.                                                
   EVAL SndMsg                                                            
   SNDMSG =                                                              
            ....5...10...15...20...25...30...35...40...45...50...55...60
       1   'yada                                                        '
      61   '                                        '                    
    
   I would expect to see SNDMSGSIZE = 0000000004.
