The effective precision (p,q) of the decimal constant zero is (1,0). When a decimal constant of precision (p,q) is converted to a string, an intermediate string of length p+k+3 is created, where k is the of digits expressed by q; hence is this case the string has length = 4; the character '0' is right-justified in it, the rest of the positions being spaces. When assigning it to the target STRING_1, it is of course truncated to the length of STRING_1, viz., 3; those three positions are all spaces. Q.E.D.
