/* Test usage variation of gettype() and settype() functions:
settype() to null type.
Set type of the data to "null" and verify using gettype
Following are performed in the listed sequence:
get the current type of the variable
set the type of the variable to "null type"
dump the variable to see its new data
get the new type of the variable
