...
get shell"divest -r -s BOB > Hfund"
if the result <> empty then
   ### did not work somehow...
end if
...

This is the syntax...

You could check the hilites of these checkboxes (maybe in a loop) and 
create the
apropriate string for the shell command like:

...
put "divest" into the_shell
if the hilite of btn "flag1" then put SPACE & "-r" after the_shell
if the hilite of btn "flag2" then put SPACE & "-s" after the_shell
...
if fld "outputfile" <> empty then put SPACE & "<" && fld "outputfile" 
after the_shell
get shell(the_shell)
...

You get the picture...

Sounds like a good idea to me :-)

So one can also learn about the different flags for the different 
commands ;-)

> Any suggestions are appreciated.

You could create different sets (read: groups) of checkboxes for the 
commands
and show/hide these sets accordingly...

Should be pretty easy...

Drop a line or two if you need more info/assistance :-)
