PAR_CANCL - Cancels a parameter    

Description:
The named parameter is cancelled. A subsequent attempt to get a value for the parameter will result in a new value being obtained by the underlying parameter system.

Invocation:
CALL PAR_CANCL( PARAM, STATUS )

Arguments:
PARAM = CHARACTER*(*) (Given)
The name of the parameter to be cancelled.
STATUS = INTEGER (Given and Returned)
The global status.

Notes:
The routine attempts to execute regardless of the value of STATUS. If the import value is not SAI__OK, then it is left unchanged, even if the routine fails to complete. If the STATUS is SAI__OK on entry and the routine fails to complete, STATUS will be set to an appropriate error number, and there will one or more additional error reports.
