When you need just trim 1 element, use 'RTRIM(MyArray(nIndex) )'
For all array items no way except lop through array:

local lnIndex, lnCount
m.lnCount = alen(MyArray)
for m.lnIndex = 1 to m.lnCount
  MyArray[m.lnIndex] = rtrin(MyArray[m.lnIndex])
endfor

>How do you trim the blanks out of an elememt of an array?

>the to trim right side of this element...
