$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.
