TRANSLATE STATEMENT

We are doing Unicode upgrade from 4.7 to ECC.

DATA: letters(20) TYPE C VALUE 'abcabcabcXab',

change(2) TYPE X VALUE '7F20'.

TRANSLATE letters USING change.

WRITE letters.

It gives Unicode error in TRANSLATE statement.

saying 'change' should be of type 'c'.

Please let me know, how this translate statement would have performed in 4.7 version.

Would it have changed any value or not.(The value specified in variable 'letters' is an example)
