Invalid Parameter.  Use "I" option to query shell type.

      Meaning and Cause: A user has attempted to enter an invalid
                         parameter at the command line with the
                         workstation shell COM  filename.

      Solution:  If the shell is to be loaded, no option  parameters can
                 be included with the shell name on the  command line.
                 If the user desires to query the shell type,  the "I"
                 option should be used after the shell name on the
                 command line.  No other option parameters are valid.
