Check whether a GKS error has been reported since the last time this routine was called. If it has, set STATUS to GKS__ERROR, and cancel the GKS error state.

CALL GKS_GSTAT ( STATUS )

STATUS = INTEGER (Given and returned)

The global status will be set to GKS__ERROR if GKS has reported an error; otherwise it will be unchanged. If the given value of STATUS is not SAI__OK, then the routine will return without action.
