How to convert character value to binary value and assign to another binary value using data step?

Defense — Thu, 01 Sep 2016 01:50:43 GMT

My_table has two fields, one is defined as [c_array] char(20), with values like ‘123456781ABCD234’. Another field is defined as [b_array] binary(8). The task is to convert value of c_array into binary and assign it to b_array.

thanks

Beware of truncation. 20 hexadecimal numbers will require at least 80 bits of binary storage.

Are you doing a hex to binary conversion like @PGStats suggested, or a char to binary conversion? If hex-binary, given the length is 20, you may need to read it in as hex one digit at a time, and spit it out as binary, then concatenate them together to the length of 80. If char-binary, there is a format $binaryw. you may need to use.

Take a look at format/informat $binaryw and binaryw.
