Hi, From SAS documentation, The TRANWRD function replaces all occurrences of a given substring within a character string. The TRANWRD function does not remove trailing blanks in the target string and the replacement string. TRANWRD uses a single blank instead when the replacement string has a length of zero. Try using compress to remove all the blank spaces,if you want. data _null_; string1='*' || compress(tranwrd('abcxabc', 'abc', trimn(''))) || '*'; put string1=; string2='*' || compress('abcxabc', 'abc', '') || '*'; put string2=; run; Thanks, Shiva
