第58题答案选的是D，但是在Prep Guide ADV参考书上722页上的解释
“The YES or CHAR setting for the COMPRESS= option uses the RLE compression algorithm. RLE compresses observations by reducing repeated consecutive characters (including blanks) to two-byte or three-byte representations. Therefore, RLE is most often useful for character data that contains repeated blanks.”
“BINARY can also be very effective with character data that contains patterns rather than simple repetitions.”
所以正确答案应该是B
