HISSET

Sets the NDF history update mode

Description:

This task controls the level of history recording  in an NDF , and can also erase the history information.

The level is called the history update mode and it is a permanent attribute of the HISTORY component  of the NDF, and remains with the NDF and any NDF created therefrom until the history is erased or the update mode is modified (say by this task).

Usage:

hisset ndf [mode] ok=?

Parameters:

MODE = LITERAL (Read)
The history update mode. It can take one of the following values.
"Disabled" –- No history recording is to take place.
"Erase" –- Erases the history of the NDF.
"Normal" –- Normal history recording is required.
"Quiet" –- Only brief history information is to be recorded.
"Verbose" –- The fullest-possible history information is to be recorded.

The suggested default is "Normal". ["Normal"]

NDF = (Read and Write)
The NDF whose history update mode to be modified or history information erased.
OK = _LOGICAL (Read)
This is used to confirm whether or not the history should be erased. OK=TRUE lets the history records be erased; if OK=FALSE the history is retained and a message will be issued to this effect.

Examples:

hisset final
This sets the history-recording level to be normal for the NDF called final.
hisset final erase ok
This erases the history information from the NDF called final.
hisset mode=disabled ndf=spectrum
This disables history recording in the NDF called spectrum.
hisset test42 v
This sets the history-recording level to be verbose for the NDF called test42 so that the fullest-possible history is included.
hisset ndf=test42 mode=q
This sets the history-recording level to be quiet for the NDF called test42, so that only brief information is recorded.
