This is just the same as if you chose any of the other tool buttons on
the MI "Main" toolbar. It stays active till you select another
toolbutton. So, yes, in a way; it's not so much a "pause" as waiting
for you to do something with the toolbutton, i.e. click on the map.
Now, if you have other buttons to click, or, Say, a dialog (where you
have to click OK to dismiss it) then it's likely another button will
have been selected. In this case you'll have to reselect your original
to start the process over.
If you had, say, a logical flag in your prog then you could perhaps use
the same tool to select your centreline point. The flag could be
set-reset wiyth each use, denoiting whether it's getting the start or
centre point. I mean, the proc outlined is essentially just a
"point-getting" routine and could equally be called GET_POINT :-)
Sub GET_POINT
' ___________
Dim lnX, lnY as Float,
...
Set CoordSys Window FrontWindow()
lnX = COMMANDINFO( CMD_INFO_X)
lnY = COMMANDINFO( CMD_INFO_Y) ' where've we clicked?
llStartPoint = not llStartPoint ' Toggling usage of the
tool
If llStartPoint then
... Code to process start point co-ords
Else
... Code to process start centreline point co-ords
End If
...
And you're welcome.

Great thanks Terry
Do you know... Will this allow the program to Pause I guess to allow the
user to click on the map. So I can have essitially one pushbutton and
then a series of promts though out the process for the user to select
columns and eventually the centreline point. Or does one process need to
stop and the user then click on a new button to continue?
I was hoping to have just one button but I can create a complete button
pad if I need to for each step in the process.
Thanks again for your help
Carolyn

Below are a few snippets to help. I've assumed a buttonpad to select a
tool that you click to get the co-ords. Selecting the tool "primes" the
procedure GET_START_POINT, such that when you click the map it "fires",
thus getting the start x/y into float vars. Then do your pipelining
stuff.

Hi list
I have searched the archives because im sure ive read about this in the
past but I cant seem to find what I need.
Basically im writing a tool that will build a pipeline between a serious
of centreline points. I need for the user of the tool to be able to
select the beginning centreline point for the creation of my pipline.
The first part of the program creates the points, im then looking to
allow the user, while the program is running to selelct the start point
and the program will continue running from there to create my lines.
I really just need to take the x and y coordinates from the users
selection and place that information into variables to begin the second
part of the process.
Can anyone help me?
I hope this makes sense.
Regards
Carolyn Bergin
