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.
