Don, it's not that the %TRIM is implied. It's just that with varying
length fields, you (probably) wouldn't have any blanks that would need
trimming.
D varfld s 10a varying
D fld s 10a inz('12345')
c eval varfld = 'abc'
* varfld has a length of 3, no trailing blanks
c eval varfld = 'abc '
* varfld has a length of 4, 1 trailing blank
c eval varfld = fld
* varfld has a length of 10, 5 trailing blanks
c eval varfld = %trim(fld)
* varfld has a length of 5, no trailing blanks
So depending on how you loaded varfld in the first place, you may or may
not need a %trim when you do your concatenation.
