$UPCASEw. format
We all know the importance of UPCASE function in handling the character case strings. But do you know that a format can let you do the same as the UPCASE function (upcasing the variables). $UPCASEw . format works similar to the UPCASE Function. It also does one more thing which UPCASE function doesn’t. i.e: $UPCASEw . format let you apply length to the variable. Remember that w specifies the width of the output field. Example: *********************************************************; data new; *convert it to uppercase; name=" studysas blog "; format name $upcase .; newname=put(name, $upcase32 .); *Put function let you apply $upcase format; run; **********************************************; *The length of the new variable newname will be 32.
