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'

After the file write I have [<ed> in hex over\under view]

TEST MESSAGE ... ---
ECEE4DCEECCC4444444444444 ... 44444444444444444444444444000
3523045221750000000000000 ... 00000000000000000000000000000

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

Whatever data is stored in the record\row of the database file field, beyond the defined length of the data in that field, is moot. Since that data is not retrieved on a read, there should be no concern for what might or might not appear there. There is no requirement for the database to store [in the dataspace] nor to show\present any consistent value [e.g. space or null character] for what is not part of the actual data.
