TRIM(x,y) is a string function that removes all of the characters specified in the character string y from the start of the character string x. The result of TRIM(x,y), therefore, starts with the first character that was not specified in y.
TRIM(x,y) also removes the blanks (code attribute ASCII, UNICODE) or binary zeros (code attribute BYTE) from the end of the character string and then all of the characters specified in the character string y. The result of TRIM(x,y), therefore, ends with the last character that was not specified in y.
