Unsqueezed Type R←181⌶Y
Y is any array.
The result R is an integer scalar that indicates the type in which Y is stored, using the values listed for monadic ⎕DR.
181⌶ is identical to monadic ⎕DR, except that it does not squeeze Y into a smaller internal representation. Monadic ⎕DR squeezes Y unless Y is data converted by dyadic ⎕DR to which no function that changes it has been applied. If a workspace compaction occurs during the execution of 181⌶, then Y can still be squeezed before its type is identified.
