IMG_CANCL- Cancel an image/parameter association

Description:
This subroutine may be used to free the resources associated with an image. Its behaviour is similar to that of IMG_FREE, except that it also removes the association between an image and a parameter. If the same parameter is later used to access an image, then a new image will be obtained (whereas if IMG_FREE is used the original image will be re-accessed).

Invocation:
CALL IMG_CANCL( PARAM, STATUS )

Arguments:

PARAM = CHARACTER * ( * ) (Given)
Parameter name, specifying either the individual image/parameter association to be cancelled, or '*', indicating that all such associations should be cancelled.
STATUS = INTEGER (Given and Returned)
The global status.
