Having a macro prompt for variable input

[Justin Walker-3]

I have a number of macros where there is a threshold step.  Since the
auto threshold doesn't choose appropriate limits, I have the limits
hardcoded into the macro, but since they change from day to day, every
time I run the macro, I have to open it, change the numbers, save,
install, then run the macro.

Is there any way I could put those limits in as variable and have ImageJ
pop up a dialog box asking me to input limits when the macro is run?

Thanks

Thanks! That's exactly what I was looking for.
