  If I'm not mistaken, id data_in is blank this code will bomb on the last 
statement.  A simple IF data_in <> *Blank statement will avoid that.

  Also, the hardcoded "40" in the 2nd EVAL should be converted to %len( 
data_in ) for flexibility and the variable "length" s/b made larger and 
made into an integer or unsigned integer.
