OPTYPE
Type: Adverb      (String*4)
Use:  To specify the operation to be used by a task or verb.  This
      adverb is similar to OPCODE and is used to avoid having everything
      use OPCODE.   See the task help files for the meaning of allowed
      values which are listed here.  A listed value of ' ' generally
      means anything else causes a default operation.

Null Value:   '    ' but interpretation depends on task or verb.
