### NDF_HSMOD

Set the history update mode for an NDF

#### Description:

The routine sets the mode to be used for updating the history component of an NDF. This allows control over the amount of history information subsequently recorded. It also allows history recording to be disabled completely.

#### Invocation

CALL NDF_HSMOD( HMODE, INDF, STATUS )

#### Arguments

##### HMODE = CHARACTER $\ast$ ( $\ast$ ) (Given)
The history update mode required: ’DISABLED’, ’QUIET’, ’NORMAL’ or ’VERBOSE’. This value may be abbreviated, to no less than three characters. In addition, ’SKIP’ may be supplied. This is similar to ’DISABLED’, in that no history record will be added to the NDF when the NDF is closed. However, ’SKIP’ makes no permanent change to the update mode - the next time the NDF is accessed it will have its original update mode.
NDF identifier.
##### STATUS = INTEGER (Given and Returned)
The global status.
