How are you reading it into a iolost?
READ DATA FROM g'RowData$ TO IOL=g'LoadIOList$
if so then the spaces are stripped because the grid iolist will be something like field1:CHR(sep)...
This means it is delimited and trailing spaces will be stripped.
If you look at g'RowData$ directly you will see the spaces are there it is converting them to the iolist where they are lost.
The best solution depends on what you want to do and your existing code but 'rowdata$ and 'value$ will both have the spaces.
