routine sets a new value for the TITLE component
of an existing NDF
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.
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.
settitle ngc1068 "NGC1068
with a B filter" Sets the TITLE component of the NDF structure ngc1068 to
"NGC1068 with a B filter".
settitle ndf=myspec title="Ice band, short
integration" Sets the TITLE component of the NDF structure myspec to be
band, short integration".
settitle dat123 title=! By specifying a null
!), this example erases any previous value of the TITLE component in the
NDF structure dat123.
