C.11.5. - Entering options
If you give a dot
. as the command-line argument or in response
to
Scans/options, the same argument or option string will be used
as last time.
That is, the string is remembered, not the options
chosen interactively using
Change modes?
For instance, if
you enter a long sequence of scan numbers and read in the scans,
then change something via
Change modes?,
you can simply enter
a dot in response to
Scans/options and recover the previous
sequence of scan numbers.
When you do enter a string of flags and scan numbers, the modes set by the flags only apply to the scans that follow the flags, not tp the preceding scans.
