It shouldn't matter. At the top of 'toolbar.dat', you'll see the
number 327, indicating the number of toolbar options that Guide is
actually using. Beyond that are a mix of functions that either don't
work, or aren't especially useful. (For example, do you really want
a specific "Go to Enceladus" button?). Some are specific to the DOS
version of Guide.

Most of the functions _do_ work and are used inside Guide. For example,
there is a function 2518 to toggle display of the Sky Atlas 2000 page in
the legend. But that function is invoked through the 'legend' dialog,
rather than through a toolbar button.

As described at the bottom of 'toolbar.dat', a person can rearrange
things in Guide to get such buttons to work, if you actually want to.

(The "Get NIST Time" function is almost completely useless. It was
something I used years back to test out serial port communications,
which I needed for telescope control. It would call a computer in
Colorado via dial-up modem and get the current time. But the real
purpose was just to verify that the COM port routines actually worked
without having to set up a telescope.)
