Re: VARLEN question

1) Why would you bother to be looking passed the assigned length?
There's no guarantee as to what the rest of the field will contain.
2) Why are you using a DS overlay to handle variable length external
fields instead of using RPGIV's native support of them?

I have a file with a zone defined as    9000                 VARLEN(100)



In the programme I set this varying length field as follows





    D   i             E DS                  EXTNAME(Fccin1 ) qualified

    D   ljZVarLen                    5I 0 OverLay(IN1ZPARVAR  : 1)

    D   ljZVarChr                 8998    OverLay(IN1ZPARVAR  : 3)

              // Data

         i.ljzvarchr = %trim(zpmess)       ;

    // Length

         i.ljzvarlen = %len(%trim(zpmess)) ;





In ZPMESS I have 'TEST MESSAGE'



Aftre the file write I have



TEST MESSAGE                                                      ----

Why do I have 5O+ blanks between the end of the data and the first null
(in yellow)





Thanks in advance
