SETTITLE - Sets a new title for an NDF data structure

Description:

This routine sets a new value for the TITLE component  of an existing NDF  data structure. The NDF is accessed in update mode and any pre-existing title is over-written with a new value. Alternatively, if a `null' value (!) is given for the TITLE parameter, then the NDF's title will be erased.

Usage:

settitle ndf title

Parameters:

NDF = NDF (Read and Write)

The NDF data structure whose title is to be modified.

TITLE = LITERAL (Read)

The value to be assigned to the NDF's TITLE component (e.g. "NGC1068 with a B filter" or "Ice band in HD123456"). This value may later be used by other applications as a heading for graphs and other forms of display where the NDF's data values are plotted. The suggested default is the current value.

Examples:

settitle ngc1068 "NGC1068 with a B filter"

Sets the TITLE component of the NDF structure ngc1068 to be "NGC1068 with a B filter".

settitle ndf=myspec title="Ice band, short integration"

Sets the TITLE component of the NDF structure myspec to be "Ice band, short integration".

settitle dat123 title=!

By specifying a null value (!), this example erases any previous value of the TITLE component in the NDF structure dat123.
