<lang algol68># declare a string variable and assign an empty string to it #
STRING s := "";
# test the string is empty #
IF s = "" THEN write( ( "s is empty", newline ) ) FI;
# test the string is not empty #
IF s /= "" THEN write( ( "s is not empty", newline ) ) FI;
# as a string is an array of characters, we could also test for emptyness by #
# checking for lower bound > upper bound #
IF LWB s > UPB s THEN write( ( "s is still empty", newline ) ) FI</lang>
